Do you have measurements in grams? The exact measuring spoons you use are not available and I would like to have the option of measuring on a scale.
My own story: I am in my 30s and the mother of four young children. I’ve been feeling dizzy on and off depending on my head position for the last three months. I drank Fiji water just for a treat, not expecting anything, and the dizziness went away immediately. I searched around to try to find what’s so magical about this water and found your blog.
Thanks for sharing your story. I am glad the silica water helped you. You can find the measurements in the recipe. https://prevent-alzheimers-autism-stroke.com/silicade/
Please can you help. I need sodium silicate to make ‘pool water’ but sodium silicate powder is completely unavailable in Ireland. You can only get ‘water glass’ liquid which is apparently SiO3 and not the required SiO2. As a family of 5 we are sick a lot , 3 of us with autoimmune conditions and a girl with possibly undiagnosed ASD
Is there anything that can be done ?
Many thanks
You can not use water glass to make Silicade as it is difficult to measure and is dangerous. Many people have used a company that gives you an address in the US to order the sodium silicate.
Good afternoon
Can I make 5 gallon of water at once . What would I have to watch out for?
We are going to start selling our kombucha commercially..our fermentation pot is 14 gallons.. therefore mixing 5 gallons at a time would surely decrease our time making a batch of kombucha..
Looking forward to your suggestions..
Gerry
You can make more than 1 gallon of Silicade at a time. Make sure your calculations are correct. Check them a few times. Some people have purchased the large Brita filter ‘tank’ which uses the standard/original filter for making more than 1 gallon of Silicade. Laurie
Thank you so much for your book Prevent Alzheimer’s and for this website.
Would you be willing to develop and post at your website a method for making Silicate from distilled water?
That would be very helpful to our family.
Thank you so much for your consideration,
Is it safe to drink Silicade to reduce aluminum levels while breastfeeding? I am not aware of the mechanism with which the aluminum binds and is excreted. Thank you.
Not only is it safe to drink Silicade while breast feeding it will have benefits for your child as well as you. During pregnancy the mother gives her silica to the fetus(see research below). The form of silica found in Silicade forms a tight bond with the aluminum which detoxifies it as well as facilitates the elimination through urine and sweat. excerpt from Dennis’ book. “Kristien Van Dyke in 2000 measured the silicon (OSA) content of blood serum in different aged individuals486. She found very high levels of OSA in infants less than a year old and extremely low levels in pregnant mothers. Van Dyke came to a startling conclusion:
“The explanation of the high silicon levels of the infant group, especially (<1yr), may be that pregnant mothers offer their silicon to the growing fetus …”” 85.

Anecdotally, I have heard of kids with dyslexia whose dyslexia improved considerably after drinking silica water for several months. Is there a mechanism by which silica water would improve dyslexia?
Hi Heather, This is Laurie and I have an answer from Dennis for you regarding the mechanism. I ran a facebook group for parents with children who had Autism and I got a report of a child’s reading improving from removing aluminum. “My 9 year old son has really struggled with reading. All of the sudden his reading skills have just taken off!! To the point his teacher wanted to talk to me after school! She said he has improved so much in the past 2 weeks she wanted me to know how proud she was of him! It is amazing he has only been on the silica water for about 6 weeks so I can’t wait to see what the future holds.” February 2018
Below is an excerpt from the book Dennis is currently writing.
Aluminum causes lesions in nerve fibers. Tau is a structural protein in nerve fibers that normally exists as bundles of tau. Breakage of tau bundles causes lesions in nerve fibers. In the presence of aluminum, tau in bundles becomes hyperphosphorylated and a soluble pTau236 (236 is the position on tau that is phosphorylated) is dissolved from the bindles one fiber at a time. Since pTau236 was rapidly dephosphorylated by endogenous phosphatases in the human fetal brain, it was proposed that the hyperphosphorylation of tau is due to inhibition of phosphatases276,277. Aluminum does inhibit phosphatases, such as PP2A, directly and indirectly by inhibiting Pin1 resulting in higher-than-normal levels of pTau217, pTau181, pTau236, and six other phosphorylation sites on Tau223,224. Dennis N Crouse
I have been reading “Prevent Alzheimer’s, Autism and Stroke:”
I find it authoritative, but there are two errors that cause concern.
1) In “The Case of the Cloaked Assassin”, you say
“I just read on the internet in the Journal of Medical Case Reports 8:41 (2014) of the strange death of a 58 year old man with no prior medical history who was diagnosed with early-onset AD. … In 2011, after his death due to AD at age 66, the frontal lobe of his brain was analyzed for aluminum.”
Did he die at age 58 or 66?
2) Your detail section about “Siliceous Organisms and their Contribution to OSA in Drinking Water”, says that
“Geologically the Malacca Strait belongs to the Sunda Shelf that was an extensive low-relief land surface formed at the beginning of Quarternary time about 2.6 million years ago. The Sunda Shelf has remained undisturbed by coastal movements for about the past 7 million years.”
How can a Shelf formed 2.6 million years ago remain undisturbed for 7 million years?
Thank you for finding these typos. I have noted the correction and will make the changes next time I update the book.
Dennis
I know that altering the recipe is a bad idea but this seems like it’s not altering it… I hope I’m not wrong! And I can’t find this asked/mentioned anywhere:
The recipe calls for
– Boil the water for 30 seconds
– Add cold water immediately
– Add to 1 gallon container
But couldn’t it also be:
– Add some cold water to 1 gallon container
– Boil the water for 30 seconds
– Immediately pour into 1 gallon container
That seems like it achieves the same thing but without needing to pour cold water into a Pyrex container (which I’ve known to shatter!).
Thank you!
Dennis has been making Silicade for at least 10 years and the pyrex measuring cup has never ‘shattered’. The reason for adding water to the boiled mixture is to rinse out the measuring cup which makes sure you get all the sodium silicate into the Silicade. Laurie
Thank you Laurie!
Dear Dr. Crouse:
Thank you for your books! I loved your “Secret to Healthy Longevity” and I’m now reading “Prevent Alzheimers, …” On pg. 223 you list the 7 supplements you recommend. I just returned from Sprouts Market in Chula Vista, CA. I ended up selecting a few of their products that sounded like what you were recommending. However, there are so many different varieties that it’s unlikely that I bought exactly what you recommend. I’d like to ask you to please go to a Sprouts near you and take pictures of the exact supplements you’re recommending. Probably the best way to help us readers purchase exactly what you’re recommending is to add a chapter in your next edition of the book that includes pictures of the recommended supplements together with explanations on the additional ingredients and options so we can know what to look for. You could even include this chapter on your blog. Once again, thank you Dr. Crouse. I’m looking forward to reading all your books.
Great you are buying the supplements. I hope you are also drinking silica rich mineral water. There is a table of the supplements with brands to buy in the Crouse Protocol blog post. The table can also be found on Page 215 of the Increasing IQ book. If you are on facebook I have a group and “what to buy” is discussed in the group. I have posted photos of the supplements I use. Laurie
Thank you for your work.
My local mineral water – I am using Kyneton Rotunda spring from the table at the link below – it has 100mg per liter silica but the ph is about 6. I read on the recipe for silicade that the ph needs to be between 4 & 5 Then further down other pH are cited ~ 6.5, 6.6 etc ~ what is optimal?
My spring water – Kyneton Rotunda – from the list in this table:
https://www.mineralspringsvictoria.com.au/mineral-composition
What does this mean for the benefit of my mineral water? – for chelation –
Do I need to add sodium bicarbonate to my mineral water to bring the ph to between 4 & 5?
Steps on the website cite other pH when other minerals are added to the silicade. Does this mean that my pH is fine as a mineral complex water?
The instructions on the website at #5 & #6 – notes a pH of 6.5 & 6.6 ~ so I’m a little confused as to wherether or not I need to amend the pH of my mineral water to be effective.
I hope you can dispel my confusion.
Thank you for all your support,
Barbara
This water has enough silica in the form of OSA to remove aluminum (160 ppm). A pH of 6 is fine. You don’t need to change the pH of this water. Laurie
Is it normal to have white chalky residue in the top chamber of the Brita after filtering, and also on the bottom of the sauce pan we’re using to boil? Or is that a sign that I have not boiled long enough to dissolve the silica powder? I do time 35s after I see the water has started to boil before shutting off the stove, and then I immediately pour in a cup of water to cool the solution. Should I be starting the timer after the entire pot is at a roiling boil? Since it’s only 1 oz of water, I’m nervous I will boil too much of it off.
A second question is whether we would achieve faster results by drinking more than 4 cups per day? Would that exceed what our body can absorb, or would it cause dangerous side effects from chelating too quickly?
The residue you are seeing is from the insoluble impurities in the sodium silicate. The purity of Sodium Silicate is 99.5%. You don’t need to change how you are boiling the solution. There is not data on whether drinking more than 4 cups a day of silica water will remove more aluminum. You can drink as much as you want as there are areas of the world where the drinking water is naturally rich in silica and in these areas people live longer and have less heart disease and less dementia.
Dear Mr. Crouse.
Thank you for your interesting book. I read the green one, about increasing IQ etc.
As an orthomolecular therapist myself I try these kinds of making things before giving it to my patients.
I try to order the ingredients for the Silicade!
Baking Soda, I have it.
Sodium bisulfate: I can order it from Amazon.de, maybe not the 99,5% pure but 93% pure…
And the Sodium Sulfate is the main problem. The powdered form.
It seems not to be possible to order from Holland, Europe.
I learned about those shipping agencies like MyUS, USAtome etc.
But I got the message that the account should be on the same address, in the USA…
So there my options stop…
Do you know anywhere to get these silicates in Europe?
So I read about the option you do not recommend, with the waterglas.
Can you send me the specific instructions to use waterglas for it?
With your info on page 227 I wonder if I can just replace the sodium silicate with the waterglass and proceed as the instructions.
I did not yet calculate the mol-amounts. Would it be possible to do it that way?
Hope to hear from you!
Kind regards,
Alderina Dill
Hello can I use Evian water as an alternative to Fiji water?
No Evian water does not have enough silica in the form of OSA (orthosilicic acid) to remove aluminum. Dennis has tested this water.
You can check out the list of waters that have enough silica to remove aluminum. Here is a link.
Bottled Silica Waters from around the World
I started giving the silicate water to my granddaughter. My daughter has also been giving her Pure Body Zeolite spray and also Fulvic. Should she stop giving that to her? Can it be harmful? She read it detoxes heavy metals. Please let me know how to proceed with the zeolite and fulvic.
Thank you!
Great your granddaughter is drinking silica water. She should stop the zeolites because in the pH of the gut zeolites release aluminum. Your daughter should read my husband’s book Increasing IQ…. as he talks about how to safely remove metals and toxins from your body. It is called targeted detox. Which means you take something that is essential for or made by your body to remove a toxin. The “essential” forms a tight bond with the toxin which detoxifies the toxin and facilitates its removal from the body. Here is a link to the zeolite write up. I will also post a link to a video I made on targeted detox. You can also find targeted detox write ups at my husbands blog on blogger. https://prevent-alzheimers-autism-stroke.blogspot.com/2018/12/saftey-of-ingesting-zeolites.html link to you tube video on targeted detox.
I bought Beryler measuring spoons,, but also need to know where to buy the OSA silica, and how much to add to what amount of filtered water, can somebody help me?
Here is a link to the recipe. This has the information you are looking for. https://prevent-alzheimers-autism-stroke.com/silicade/
Hello
Thank so much for the valuable alzheimers info.
In Norway one can just get the new Brita filter, marella: https://www.brita.co.uk/water-filter-system/water-filter-jugs/marella
Do you have any idea of this is so much better for filtering that it filters away the OSA?
It is supposed to filter 20% better than previous it claims.
Best regards
Henning
Regarding the new Maxtra Pro. The description says they have added a fine mesh to the bottom of the cup. This change would not effect the removal of aluminum or the retention of silica. We have purchased this filter and will test it sometime in the next few months.
Thank you Sir. I have now bought your book aswell. Just a suggestion; you may would consider releasing a recipe on “How you test the water for OSA” if possible. Then your Silicade recipe could outlive both me and you, because then people can test OSA content made by the coming Brita filters which will appear in future, aswell
This has already been done. The procedure for testing for OSA is described in the Silica Water book Appendix IV.
Regarding testing future filters, in addition to testing for OSA you would also need to test the amount of aluminum removed by the filter. The procedure for testing aluminum is in Table 14 of the Silica Water book.
You can also test OSA at home with a HACH Silica Test Kit, Model SI-7 https://www.hach.com/p-silica-test-kit-model-si-7/2255000

Is there any aluminium free air fryers? I live in Europe.
We have not researched air fryers. If you find one that is stainless let me know.

Hi Dr. Crouse. thank you so much for your investigation and good work on preventing disease from aluminum ingestion. I do recommend the Bunn Speed Brew coffee maker, readily available right now in the United States directly from the manufacturer. Here’s my review. https://jackbyromcom.wordpress.com/2024/06/27/review-of-the-bunn-csb2b-high-altitude-speed-brew-elite-coffee-maker/
Can I boil the prepared water for consumption?
You can heat the Silicade but you can only boil for 3 to 5 minutes. If you boil longer the silica (OSA) will come out of solution.
We had our well tested and the reactive silica content was listed as
18 mg/L
How does this compare to the part per million? Is this low?
The method they used for testing is listed as
SM 4500 SiO2 C
I also was wondering about the making of our own ortho silicic acid. After adding the chemicals, we are supposed to filter the water with a very simple filter so as not to remove the reactive silica again. What is it that we are filtering? Will a simple carbon filter remove whatever is bad? Also can we just filter the chemical mixture first and then add it to water? It would be a lot faster to filter that small amount so I was just wondering about that…
Thank you!
Your water does not have enough OSA to remove aluminum. You need to use the Brita filter to make Silicade. The filter removes the impurities in the ingredients. Here is a link to the recipe. There are reasons for every step. You need to follow the recipe. Here is a link to the recipe and explanations for each step. https://prevent-alzheimers-autism-stroke.blogspot.com/2017/09/silica-water-recipe-for-making-your-own.html
Thank you for the response!
I have been re-reading your book, trying to find the answers to the questions I had previously asked while I waited. I apologize for asking questions that are actually answered in there.
On p. 168 you have a table of Silica supplements. The Silicade is listed as Silicon content of 26.5-40.7 mg. The next column lists 39-60 mg of OSA. Those are 2 separate values, correct? Bioavailable in OSA + non-bioavailable in Silicon… And you said Silicade is identical to Fiji water for OSA content somewhere in the book, I didn’t write that one down.
So, based on that table, Silicade (or Fiji water) has 10.175 mg OSA per cup.
My well water has 18mg OSA in 1 liter so I calculate it to have 4.186 mg OSA per cup. So that is 41% of the quantity in Silicade. Am I calculating that correctly?
If so, when making Silicade, should I dilute the formula with 60% more water?
Also wouldn’t 40% take some of the aluminum out of the system? Perhaps just not enough to keep up in our toxic world? Or does it tend to get absorbed for other system uses and nothing is left to bind in the gut? If that is basically our exclusive water and we are drinking more than 4 cups per day, say double or more, than it would be helpful wouldn’t it?
There are 4.2 cups per liter and both Fiji water and Silicade have 146mg of OSA per liter. Therefore, each cup of Fiji water and Silicade contain 34.8mg of OSA.
You say your well water contains 18mg of OSA per liter and this would be only 4.3mg of OSA per cup.
The only silica waters I recommend for aluminum removal are those with 50ppm OSA minimum that is 50mg per liter or 11.9mg of OSA per cup.
To make the minimum recommended level of OSA in water you can dilute Silicade approximately 3-fold.
I have eliminated known sources of aluminum from my diet except for one. I recently learned that the Methylcellulose fiber caplets I take are colored with Yellow #6, an aluminum lake dye. I can’t find any alternative caplets without dye. There is powdered Methylcellulose without dye, but it is difficult to mix with water to drink. I have been taking 6×500 mg caplets per day. My question is whether you might have any idea of how much aluminum this represents and whether my concurrent use of silicade can adequately deal with it. I realize you won’t have a precise answer, but am looking for any kind of guidance. And yes, we should remove all sources of Al, but I find these caplets essential for maintaining fiber input and regularity.
A related question is, at what level of daily intake would Al be considered significantly toxic in terms of its contribution to Alzheimer’s? Can silicade effectively remove ingested Al in small amounts such as the caplets above such that one doesn’t need to worry about it?
Thanks for any help with this.
Hi Richard,
I had to change my fiber pills for the same reason, aluminum lake as the dye. It took me a few tries but I found a fiber pill that works better. Regular bowel movements are important for our health. I know how hard it is to try a new product when you find one that is working.
Regarding how much aluminum in the pills you are taking and will drinking OSA remove the aluminum ? I would have your aluminum levels checked by a 24 hour urine test. If your levels are low then perhaps you might decide to continue with your fiber pills, if your level is high then you might want to find an alternative. This is a personal decision. Here is a link to a write up for testing. There is a table of amounts of aluminum for a healthy adult and someone with Alzheimer’s. https://prevent-alzheimers-autism-stroke.com/2023/11/20/good-news-aluminum-levels-reduced-by-40/
Hi , would adding diluted(3%) hydrogen peroxide to the water before starting the steps or after after the process . Is it safe and will not neutralize the aluminium removal . Thanks
I have not examined hydrogen peroxide’s impact on aluminum removal by filtration. I do not recommend drinking water containing hydrogen peroxide because hydrogen peroxide is a mutagen (causes genetic mutation) and possible a carcinogen. Hydrogen peroxide produced in the body indicates an inflammatory response to an environmental toxin such as aluminum or a microorganism such as a bacteria or virus. Continuous exposure to hydrogen peroxide increases the probability that a pathogen will mutate to a more potent form. The body uses hydrogen peroxide acutely to cause lethal mutagenesis of unwanted pathogens. Here is a link to more information on why you shouldn’t drink hydrogen peroxide.
My mom has vascular dementia and has been on Aricept for
8 years! Even though the doctors tell me it usually is only effective for 1-2 years average, they are concerned if I take her off it, her dementia will rapidly get worse. What are your thoughts on this? I’ve been wanting to take her off this for a long time but am scared to.
Keeping her on Aricept will also hasten the progression of her dementia. I will put a link to the research in this regard. How much cognitive impairment does she have, Mild, Moderate or Severe? Has your mother started drinking silica water ? If not you should start her with 4 cups a day and spread her drinking throughout the day. After a few months you could then take her off the Aricept. Have you taken a look at the sources of aluminum and begun to eliminate them? Here are some links. Sources of Aluminum
I have 2 questions. The first being that Silicade has a pH of 6.6. Is this because is the pH gets to 8.0 then something happens chemically that makes the Silicade not work as well?
Question 2: Can I take a gallon of the Silicade liquid and make a vitamin/mineral drink out of it. I would take the gallon of Silicade and add Tart Cherry Juice concentrate, 1 Tbsp liquid minerals, and sweeten with stevia to taste. This would make a Vitamin C drink with minerals that would also selectively remove aluminum from the brain. I already make this drink, I’m just wondering I could use Silicade as the liquid.
1. At a pH of 8 the OSA (the form of silica needed to remove aluminum) becomes polymerized and it can no longer be absorbed by the body.
2. You can add juice and sweetener to Silicade. However, you should not add the liquid minerals as they most likely contain aluminum. Minerals extracted from the great salt lake contain aluminum. Also the purity of mineral drops is a concern. Personally I would get my minerals from taking a vitamin or adding calcium and magnesium (amounts as per the recipe) to Silicade.
Laurie -Dennis’ wife
Sodium aluminum silicate is used as an anticaking agent in some salt brands. Have you done any research on aluminum content in table salt brands?
I know Morton salt uses Calcium Silicate as the Anti-Caking Agent. I have not done any further research in this regard. Have you found any brand(s) of salt that contain sodium aluminum silicate or sodium aluminosilicate ?
Hi, I checked my water that I use to prepare Silicade and it is low in calcium and magnesium. I followed your recommendation and got the calcium chloride and magnesium chloride hexahydrate from Loudwolf. Do I add them directly into the prepared Silicade water or should I add them in the step to be also filtered through the Britax filter to remove any impurities? The calcium chloride reads “food grade”and 99% pure, and the magnesium chloride reads “reagent grade” and 98+% pure.
The sodium bisulfate “reagent grade” is also filtered before consumption.
Thank you so much for your advise!
Add the magnesium and calcium at the end of the recipe. Do not add them before the filtering step. There is another magnesium from Loudwolf you can use if you are looking for another source. Magnesium Sulfate Heptahydrate which 99.9 % pure. The Calcium chloride from Loud Wolf is food grade and 99% pure. The front of the bottle says 99% pure/food grade.
Hello,
I saw that the page with coffee makers includes the Braun KF7000. Before I bought some as gifts, I wanted to check in with the company to ensure that nothing has changed, so I sent an email asking if the heating element is aluminum or stainless steel. This was their response:
Thank you for your recent contact into our Customer Care Center.
We regret to inform you that all of our coffee makers are made with the following material:
– 70% Plastic.
– 15% Electrical.
– 10% Aluminum.
– 5% Glass.
Thanks Tom for this information. I have taken this coffee maker off the list. I am going to add to the coffee maker write up that people should contact the manufacturer as the manufacturing process may have changed. I also recently found out Keurig has changed their manufacturing and they are using aluminum. Perhaps if people keep writing and asking about aluminum we can increase the number of options for aluminum free coffee makers. Consumers have power.
You’re welcome, and I found a bit more info in my search:
I just received an email from Beautiful that says, “The heating element is SECC material, it’s steel metal coated with zinc.” This is the one that I’ll be giving as gifts and I’m very appreciative of the work that went into finding this!
The Krups unit doesn’t appear to be in production anymore. It isn’t on the Krups website, but it shows up on searches on some storefronts that look rather questionable. I passed for that reason.
This is the message that I received from Capresso: “The MG900 is discontinued. We no longer have a machine with stainless steel heating element. Please visit our website at http://www.capresso.com to view machines.”
My assumption about the Bunn is that it probably has a steel heating element since their specialty is making commercial coffee makers. Ironically, that’s why I decided against it. The design necessitates that the unit has a constant tank full of water that must be kept heated to produce coffee on demand. Reading reviews, if you don’t follow the unique instructions to use it, you can destroy it and void the warranty.
Thanks again!
Thanks for the update and information. I hope everyone is happy with their new coffee maker. Laurie
I have another coffee maker to potentially add to the list: the Behmor Brazen. The beauty of this is that there’s little room for hidden aluminum. It has a stainless steel water reservoir that sits at the top. When the water is heated, it’s released into the coffee basket directly below, and from there it drops into the carafe. This is a great design for those who want to keep their brewers clean, descaled, and free from bacterial growth. It also has some remarkable features and many rave reviews.
This coffee maker will be added to the list. Dennis recently tested a Behmor Brazen Plus 3.0 and no aluminum is added to the coffee. “Good news. There is another aluminum free coffee maker. Behmor Brazen plus 3.0. Dennis tested this coffee maker and no aluminum is added to the water. $199.00
Dennis has been making coffee with this machine and it makes a good cup of coffee. Features he likes. The machine presoaks the beans. You can program the amount of time to soak the beans and you can also set the temperature for brewing. It is easy to use. You can make 1 cup or several cups of coffee.” Laurie
Hi, I have a 3 year-old with ASD who will not drink plain water. If I dilute a small amount of apple juice in Fiji water, will it have the same effect in terms of removing aluminum?
Appreciate your time. Thanks!
Yes you can add apple juice to the Fiji water. The juice will have no effect on the silica which removes the aluminum.
Hello
I have read a bunch of articles, but have yet to see the actual recipe for Silicade. How can I get to it?
Also, I have a Brita pitcher that filters the water as you pour from the pitcher. I am not sure that is the device you are recommending. Can you expand on your definition of a Brita pitcher?
I would love to be able to make up a mix to add to my water jug that I drink from every day. It is around a 4 cup capacity. Is there such a thing as a concentrate or a powder mix you can just add to your water bottle?
Can I use Berkey filtered water to make the Silicade water?
You can start the recipe with water filtered through a Berkey as long as you aren’t using the Berkey Fluoride Filter. The Fluoride filter adds aluminum to the water.
You can only use a Brita filter in step 4 as it removes impurities such as aluminum while keeping the OSA (form of silica). In case you haven’t seen this FAQ about making Silicade.
You also asked about ppm – Silciade is 124 ppm of silica (OSA).
This is all so fascinating! I am an RN in the US (9 years), and also an animal nurse (28 years). I have worked, bedside (through covid), with our senior population. The rate of alzheimers/dementia/cognitive decline in our senior population is incredibly sad, and we continue to make them more ill with all these ‘medications’ and such. I was eventually fired for not complying with their injection mandate. Now I substitute as a per diem school nurse in our local schools. The kids are malfunctioning! I substitute at a school for children with autism/severe adhd, etc, and the severity and number of children with these conditions is staggering. I also substitute at our ‘regular’ public schools and am saddened by how poisoned the kids are, between all the injections they are required to have, the things that they eat, all the electronics and media they are exposed to, I truly worry for their future. And the same pertains to our pets. Shot after shot, oral and topical flea/tick/heartworm pesticides, processed cereal for food, the rate of cancer, diabetes, thyroid disease, epilepsy, cognitive decline, etc – it’s insane.
Now my question, can our pets safely drink the silica water? I wouldn’t see why not, but I wanted to double check.
Thank you for your time, Michelle D, Long Island NY
Hi Michelle This is Laurie. I share your concerns. I am a retired school psychologist and during my career I witnessed first hand the dramatic increase in Autism, children on the Spectrum and children with attentional issues. We need to get aluminum out of vaccines. Fortunately not all vaccines contain aluminum. However, children are receiving more vaccines than in the past resulting in exposure to more aluminum. Yes our pets are also being impacted by environmental contaminants.
You ask about silica water being safe for pets. During my husband’s research he looked into the risk of kidney stones from drinking silica water. For humans there is no evidence of kidney stones from drinking silica water. For dogs there is one paper which reports kidney stones from drinking silica rich mineral water. Here is the title of the paper.”Silica urolithiasis in dogs Yumi Tasaki, Genta Ito, Yasuyuki Momoi; written by (YM) Department of Veterinary Diagnostic Imaging, Joint faculty of Veterinary Medicine, Kagoshima University”
You may be very interested in reading my husbands 3rd book. Increasing IQ….. He looked at toxins children are exposed to such as aluminum, lead and mercury etc. and presented research showing the impact on children’s cognition but more importantly he found ways to safely remove these toxins with things either made by the body or essential for the body. Here is a link to the book. Some of the protocols are at his blog on blogger.
Thanks for your work and making this available to us.
Currently having issues finding Loudwolf Sodium Bisulphate CAS 10034-88-5.
Can Loudwolf Sodium Metabisulphate CAS 7681-57-4 be used in it’s place, perhaps with an adjustment of the quantity?
Hi Dr. Crouse,
I just read your article at: https://prevent-alzheimers-autism-stroke.blogspot.com/2019/07/mercury-detox-using-selenium-method.html. I am going to have my 10 mercury fillings removed by a biological dentist and he recommended detoxing using a product called Selenase which is made with sodium selenite pentahydrate (one tablet daily) and 25 mg of zinc.
I have done a lot of reading about selenium supplementation, including your outstanding article referenced above (which is making me rethink the advice given in the book Mercury Detoxification by Dr. Tom McGuire). However, all of the discussion of selenium supplementation is about Selenomethionine either in yeast or yeast-free. There is no discussion anywhere of using selenite.
My dentist takes Selenase every three months to help keep his own mercury levels down, so he trusts the product. He also says that back in 2000 he was so mercury toxic that he had hand tremors, and taking Selenase cured him of that.
However, I am still cautious since I can’t find anything about using it for mercury detox. The supplier he recommends is at this link: https://apozona.com/product/selenase-100-xl-tablets-100/. I believe the marketer is at this link: https://www.korahealthcare.com/selenase/. I believe the manufacturer is at this link, although they have only a liquid form not a tablet form on their website: https://biosynhealth.com/products/100-mcg-selenase-20-count?variant=40681389195439
I would appreciate any comments you have on this since. Logic tells me to use Selenomethionine as given in your article along with agents that can escort the inert mercury/selenium compound out of the body (chlorella, etc.). But my dentist is absolutely convinced that this German product is superior to other forms of Selenium (he learned about it from two German doctors when he was at a conference in Germany). He makes this recommendation to all his patients.
He trained under Dr. Huggins and has been removing amalgam fillings for 30 years, so he’s been around the block on the subject of amalgam removals and detox methods, and he has followed various protocols himself and determined Selenase is the best.
Thank you for your insights.
Great you found my husband’s write up on L-selenomethionine. This method is safe and effective. The L-selenomethionine forms a tight bond with mercury, detoxifying the mercury and facilitating it’s removal from the body. You do not need to take anything in addition to the L-selenomethionine. Perhaps you can have the dentist you are going to read my husband’s write up. You may want to ask your doctor for the studies showing sodium selenite removes mercury. I hope everything goes well for you. Laurie Adamson
Hi Dennis,
Am reading your “Silica Water” book and note that it recommends 3 to 4 cups of silica water per day. But would it be safe to do up to 8 cups per day (I’m using Fiji Water)? Or is there a reason not to?
I was thinking, since the half-life of OSA is about three hours, it might be good to do it every three hours ’round the clock (except maybe while sleeping).
You can drink more than 3 to 4 cups a day as you will find in the book many places in the world have drinking water which is rich in silica and these people are most likely drinking more than 3 to 4 cups a day. Thanks for reading the book. It is fascinating. Laurie Adamson
I make and drink distilled water. can I make this and add to distilled with this recipe
Thank you for the invaluable information that you provide for us, and thank you for patiently answering so many questions here. I hope you can answer my question as well. I’m assuming that when prepared properly, the OSA remains equally distributed throughout the water and does not precipitate. What I’d like to do is to prepare a 5 gallon batch using 5X the sodium silicate with 5 x 1/8 cups of water, boil it, and add it to 1 gallon of water. Mix in 5X the amount of sodium bisulfate. Add it to 4 gallons of water to bring it up to 5 gallons. If this is ok to do, can I filter this concentrated mixture through the brita or do I need to mix it with the 4 gallons of water first? One concern that I have is that I read somewhere that if the OSA concentration is too high, that kidneys stones can develop. Perhaps your book (and/or Dr Exley’s, both of which I’ll be buying) answers this question.
Thank again!
Here are instructions for making 4 gallons of Silicade. You can buy a large Brita water filter and use a standard filter. For example
For making 4 gallons of Silicade
1. Add 6 level dashes of sodium silicate to a one-cup Pyrex container
2. Add 1/2 cup of tap water to the one-cup Pyrex measuring container
3. Heat the contents of the Pyrex measuring cup to boiling and boil for at least 30 seconds
4. Dilute immediately with a small amount of unheated tap water
5. Pour all the contents of the Pyrex measuring cup into a 4 gallon container
6. Fill the 4 gallon container with unheated tap water to the 4 gallon mark on the container
7. Add 4 level dashes of sodium bisulfate to the 4 gallon container
Laurie Adamson
Thank you so much for this invaluable information! I use reverse osmosis water to make the silica water. Do I need to dilute it to 1 gallon before passing through the brita filter? It’s difficult because my family goes through 2 gallons of water a day. Also is there some sort of assay for silicic acid? Dr. Exley wrote a blog on his substack that says there is virtually no silicic acid in horsetail tea. I’ve been drinking horsetail tea and bamboo tea for years, thinking the silica is bioavailable. Furthermore, there are doctors that recommend horsetail tea to remove aluminum. It would be good to know if this is ineffective. Thanks in advance.
You can start the Silicade recipe with RO water. There is a large Brita filter you can use. Make sure you use a standard filter. Dr. Exley is correct about horsetail tea. Both Dennis and Dr. Exley have tested various silica supplements one being horsetail and horsetail does not have enough silica in the form of OSA to remove aluminum. The testing Dennis did can by found in his 1st book Prevent Alzheimer’s ……. Page 138. Here is a link to FAQ about making Silicade.
Thank you! The question I have is if I have to completely dilute it before using the brita filter because I make such large quatities of it. Much appreciation!
Here are measurements for making more than 1 gallon at a time. You would follow the recipe. I will post a link to a large Brita filter. For making 2 gallons of Silicade
1. Add 3 level dashes of sodium silicate to a one-cup Pyrex container
2. Add 1/4 cup of tap water to the one-cup Pyrex measuring container
3. Heat the contents of the Pyrex measuring cup to boiling and boil for at least 30 seconds
4. Dilute immediately with a small amount of unheated tap water
5. Pour all the contents of the Pyrex measuring cup into a 2 gallon container
6. Fill the 2 gallon container with unheated tap water to the 2 gallon mark on the container
7. Add 2 level dashes of sodium bisulfate to the 2 gallon container
8. Stir the mixture thoroughly and then filter the mixture through a Brita filter pitcher
9. After filtering, add 1 level dash of baking soda (sodium bicarbonate) to the mixture (adjust
the pH according to the recipe)
10. Stir Silicade to dissolve the baking soda
For making 4 gallons of Silicade
2. Add 6 level dashes of sodium silicate to a one-cup Pyrex container
2. Add 1/2 cup of tap water to the one-cup Pyrex measuring container
3. Heat the contents of the Pyrex measuring cup to boiling and boil for at least 30 seconds
4. Dilute immediately with a small amount of unheated tap water
5. Pour all the contents of the Pyrex measuring cup into a 4 gallon container
6. Fill the 4 gallon container with unheated tap water to the 4 gallon mark on the container
7. Add 4 level dashes of sodium bisulfate to the 4 gallon container
8. Stir the mixture thoroughly and then filter the mixture through a Brita filter pitcher
9. After filtering, add 2 level dashes of baking soda (sodium bicarbonate) to the mixture
(adjust the pH according to the recipe).
10. Stir Silicade to dissolve the baking soda
I came across your name on a Youtube presentation by Dr. Jorge Flechas. I searched and found your video on how to make Silicade. Since the Silicade is filtered through a Britta filter, would I still follow the manufacturers recommendation on filter changes or would I change the filter more often because of filtering Silicade? I hope my question makes since.
How would I find out if my tap water is low in calcium? Is there a test strip, and if so what constitutes low?
Does the magnesium option in your recipe make the sparkling water?
If I take a daily vitamin that contains calcium and magnesium, would it be necessary to add the calcium and magnesium to the Silicade?
To make sure that I reach the 6.5 pH do I need to use test strips?
Thank you for your time in answering my questions. I very excited about making your recipe and drinking it for better health. My mother also passed away from dementia in 2018 and I wish I would have known about this a long time ago.
1. Yes use the manufactures recommendation which is change the Brita filter around 40 gallons.
2.If you are in the US you should be able to find the amount of calcium and magnesium on line in the water report from the town or city’s water department.
3.Magnesium does not carbonate the water. I use a soda stream machine to make sparkling water.
4. Adding Calcium and Magnesium is optional. Check the amount of calcium and magnesium in your tap water and then decide about how much to take in a supplement.
5. Yes you can use a pH test strip. You can also buy a calibrated pH meter. There are some that don’t cost much.
I am sorry to hear your Mom passed away from dementia. Great you are taking action and making Silicade. Here is a link to FAQ about making Silicade.
Hi, in one of the videos it is stated that a Keurig coffee maker was tested and apparently added no aluminum to the coffee. Do you suppose that most or all Keurig coffee makers produced in the last 10 years do not use an aluminum heating element? Thanks! -JB.
Here is information from the Keurig company. “Keurig brewers do not have aluminum parts in the water path. The hot water tank is made of stainless steel and other water pathways are non-metal. K-Cup lids are multilayered and one of the layers is aluminum foil so if a consumer has an aluminum allergy, it is not recommended that they use K-Cup pods. We do recommend that they use the My K-Cup Universal Filter and ground coffee of their choice.” I reached out to the appropriate department regarding your inquiry, please see below for the information I was provided with. “The K400 would be a good choice for him as that system is primarily constructed with a stainless steel heater. Other brewers that would interest this consumer is K-Classic, K-Elite, K-Select, K-Café, K-Café Se, K-Compact (although this system may be more difficult to find), K-Duo Essentials, K-Duo, or K-Duo Plus. The best direct comparison to K-400 would be K-Select or K-Elite.” Is there any way you can tell us where / who in which the aluminum information was provided to you? That would be great feedback as engineering would like to know, thank you! Sincerely, Keurig Corporate Consumer Care” Dennis has tested the K cups and they don’t add aluminum to the coffee.
Thank you for the thoughtful reply regarding coffee makers.
I should note that as of April 2024 it appears that the Bunn Company of Illinois is a good place to find home coffee makers that do not heat water with aluminum heating elements. They categorically state that none of their coffee makers [including those for for home use], which is quite a collection, utilize aluminum heaters or tanks. They all use stainless-steel parts to heat and store the hot water. I have confirmed this via their chat, as well. They have some higher end, but not extremely expensive appliances for sale; for instance, one of their ”speed brew elite” models that can be delivered to your home within the United States for a total cost of about $150. They make and sell coffee makers that I think would be promising for those trying to avoid aluminum. Many of these coffee makers can also be found on amazon.com under the BUNN listing.
Dear Dennis,
Thank you for sharing your video on making your own Silica Water, I have been trying to do this but sadly here in the UK I just cannot get hold of Sodium Silicate, Low alkaline Powder at all, I’ve spent hours trying to locate some I can purchase.
I did manage to find Water Glass 40% Sodium Silicate R-145 | liquid glass which has the same cs 1344-09-8.
I’m not a chemist but is it OK to use this? I did try adding 20 drops to 2litres of water with a tiny amount of Baking Soda and the pH comes out at around 8.5, but I am unsure as to whether this is the same thing, or if it is, if I’m using the same amount.
I would be so greatful for any advice you might be able to offer, as I would love to be able to make it the same as yours but the inability to get the power form is preventing me.
As I said I’m not at all knowledgeable with the chemicals so please go easy on me.
Kind Regards
David
Hi
I’m in Canada. The only Sodium Silicate I’m able to get here (even on Amazon) is also called Water glass. Is this ok, or not? Could I modify it somehow to bring it to a low alkalinity? Also, I order my water from a Mountain Springs company here. Do I still need to pass it through a Brita filter?
Thanks
Rosalind
You can not use water glass to make Silicade as it is difficult to measure. The chemical store should ship to Canada. If not here is a site you can use to get a US address for shipping the sodium silicate. There is a blog post on FAQ on making Silicade. Yes you need to use the Brita filter to make silicade to remove any impurities found in the ingredients.
Hello,
I am from Australia and may have found a sodium silicate I can source. The ratio of SiO2:Na2O 1:2. I think I read that a good ratio would be between 2 to 3.22. Would a ratio of 2 be suitable to get sufficient OSA? or would I need to adjust the quantities..
cheers, Peter
You asked “Would a ratio of 2 be suitable to get sufficient OSA?” The answer is no. For Silicade you need the ratio of 3.22 SiO2 to Na2O. So what you have found will likely not work. The powder needs to have a purity of 99.5%. You need to perform Coradin’s Silicomolybdic Blue Spectrophotometric OSA (Si(OH)4) Assay to measure the OSA.
Hello, I was wondering if a Brita pitcher or other carbon filtration system was necessary to make the silicade for someone who is on well water?
Yes a Brita filter is required to make Silicade. There are impurities in the ingredients and the Brita will remove the impurities while keeping the silica. My husband tested several filters and Brita is the only filter that meets the requirements for making Silicade. Check out the blog post of FAQ about Silicade.
All the recommended measuring tools provided and referenced as Amazon products return search results as “none”. Any suggestions? Thanks and all the best to you.
Are you supposed to replace all your drinking water with this, or just drink a certain amount each day? I have been replacing all but thought I read something that said to drink 2-3 cups a day.
You need to drink 3 to 4 cups of silica water a day to remove aluminum from your body. You can drink more if you would like to. In areas of the world where the drinking water is rich in silica all the water they consume is high in silica.
Hello,
I’m a bit confused and hoping that you can clarify something for me.
In step 3 of the detailed instructions for silicade, it states that if your water is more basic then you can use a pH meter and slowly add the sodium bisulfate to reach the desired pH of 4.0 – 5.0 Under the section of why this solution works, it states that you render the solution non-hazardous by acidifying the solution to pH 4.0 – 5.0 with the solid acid sodium bisulfate. So, I’m assuming achieving the desired pH of 4.0-5.0 is important.
I have been making silicade using rural tap water. Do I need to be testing the pH level of my water to ensure that I’m adding the correct amount of sodium bisulfate to render the solution non-hazardous? Or, as long as I am following the directions and using the directed measurements is it unnecessary?
Thanks for you help,
Lauren
Tap water is regulated to be a pH of 6.5 to 8.5 so there is no need for you to check the pH of the water with a meter.
Great. Thanks for your quick response.
I have two questions.
1- will pouring a bottle of Fiji Water through a water filter pitcher remove some of the silica content? We use Epic Water.
2- how about boiling Fiji Water for tea/coffee?
Hi Joe, An anion exchange filter will remove the silica. The Epic water filter website does not tell you the type of filter they make. It says coconut and “proprietary”. You don’t know what the proprietary is. You can heat silica water but do not boil it. Boiling for
more than a few minutes will cause the OSA (silica) to precipitate out of solution, rendering it
ineffective to remove aluminum from the body.
Hi. I’m so excited to try your more affordable way to make silica water! I have a Berkey water filter. Can I use that instead of the Britta?
No you can not use the Berkey for making Silicade. You need to have a filter that keeps the silica while removing cations (such as aluminum) from the Silicade. Also do not use the Berkey filter that removes Fluoride as it uses aluminum oxide to remove the fluoride and in the process adds aluminum to the water. You can start the recipe with water filtered through the Berkey that doesn’t include the fluoride filter.
Hi!
I wonder if the Silica water must be consumed cold only? Or is it OK to make hot coffee/tea with it?
Best regards,
Timo
Hi Timo, You can heat silica water but do not boil it. Boiling for

Buongiorno volevo chiedere ho mia madre con Alzheimer, volevo sapere come si possono eliminare tossine alluminio piombo mercurio metalli pesanti ecc dal cervello??? esiste un modo????
Carmela, Translation. “Good morning I wanted to ask I have my mother with Alzheimer’s, I wanted to know how you can eliminate toxins aluminum lead mercury heavy metals etc from the brain??? is there a way????” You can have your mother drink silica water – 1 liter a day and spread the drinking throughout the day. Here is a list of silica waters. https://prevent-alzheimers-autism-stroke.com/2021/08/26/bottled-silica-waters-from-around-the-world/
Dennis,
I currently make Magnesium Bicarb water. I was wondering if I could mix this with Silicade, or would the two react and form another compound?
Thank you.
Jason Breedlove No you should not do this. There is an option at the end of the recipe for adding magnesium.
Wanted to know of liquid Silicon Dioxide would work? Eidon Ionic Minerals liquid silicon dioxide claims to be 375mg of Silicon Dioxide per 15ml. Would this type of silica be adequate to detox aluminum?
Jason Breedlove You can not use silicon dioxide to remove aluminum. OSA (orthosilicic acid) is the only form of silica which has been proven to remove aluminum from the body. I have tested Eidon which has colloidal SiO2 and it contains no OSA and will not remove aluminum.
Ok, thanks a lot!
Hi, Dennis. Thank you for all your research work and for publicizing this information on the internet.
The question I have for you is if I could have your permission to translate some of the articles on your site to Brazilian Portuguese. The reason for this is that I am trying to convince a beloved elderly that aluminum may be the cause of her husband’s Alzheimer’s. She likes to reasearch things by herself, but she cannot read in English. I am especially interested in the article entitled “Finding A Cause And Potential Cures For Alzheimer’s Disease – Climbing The Ladder Of Causation”.
I do not intend tu publicize this translation; however, I would be using a web-based CAT (computer aided translation) tool for this, and the article would be visible in this platform.(only for those who have an account in the plarform). Of course I would cite your name as the author.
However, if you do not wish this to be the case, I can remove the document from the platform after completing the translation.
Thanks in advance and greetings from Brazil!
Hi Bruno, I have already agreed to a translation of the Silica Water book into Mandarin which will be published in Malaysia soon. So I will grant you permission to translate a portion of the book titled “Finding a cause…………..” so the spouse of your “beloved elderly” can benefit from this information. Please keep the title of the book in English and put my full name as author Dennis N Crouse.
Hi, I have a question regarding the ingredientes.
I have found a “sodium bisulfate” in my country, Chile. but the molar weight is : 120,06 g/mol and the one that you recommend is 138,08 g/mol. I realized that the difference its the one you recommend is “monohydrated”
Is it any difference if I use that sodium bisulphate? is it the same? or should I make sure that the sodium bisulfate is monohydrated?
Thank you
The molecular weight of a chemical varies based on its hydration level. I recommend you find monohydrate so you don’t need to make adjustments. Some people have had success going through a company that will give you a US address. Here is one company. https://www.myus.com/
I have your book, and watched and read the coffee pot section
Fo u have an updated list of coffee pots thst do not sdd aluminum?
I will be testing another drip style coffee maker soon which the manufacturer says the water/coffee does not come in contact with aluminum. Beautiful 14 Cup Programmable Touchscreen Coffee Maker by Drew Barrymore. A member of my wife’s facebook group found the coffee maker.
Hi Dennis
How much sodium is in silicade, and is this a concern for longterm ingestion?
Thank you
Silicade is made from sodium silicate and sodium bisulfate resulting in a solution that is 61 ppm sodium. This is 61 mg per litre of Silicade. It is recommended you drink 3 to 4 cups(1 litre) per day of silica water. If you are on a low sodium diet it is recommended your sodium be below 1,500 mg to 2,000 mg per day. When you drink Silicade you be ingesting well below the daily limit for sodium.
Hi Dennis, Thank you for sharing your research about silica water. I would like to ask two questions about it:
1. Chris Exley said that in his experiments he trialled various silica supplements but had not observed the same benefits using any silica supplements compared to the natural form of silica waters. Is there reason to believe made-at-home silica water can work as well as Volvic, Fiji etc?
2. You recommended filtering OSA through a Brita filter and I wonder if a Berkey black filter would be OK, or if it removes/ reduces OSA?
Thank you for any tips. With kind regards, Anna
I have tested silica supplements and the amount of OSA they contain. None of them contain enough OSA to remove aluminum. Table 33 in my Silica Water book, page 165.
You can start the Silicade recipe with water filtered by the Berkey Black filter but you can only use the Brita filter when making the recipe as it removes impurities and does not remove the OSA.
I didn’t answer one of your question “Is there reason to believe made-at-home silica water can work as well as Volvic, Fiji etc?” ABSOULUTELY ! Silicade has the same amount of OSA as Fiji water. Regarding your other question, I need to do some calculations about the amount of sodium.
Hi Anna (and Dr. Crouse). I have been delighted to discover the work of these two most significant men in the world right now publicizing the dangers of aluminum, the link to Alzheimers disease (and others) and the extraordinary possibility of reversing the neurological damage of the toxic aluminum using OSA. I mean, of course, Dr. Crouse and Dr. Exley. I have bought and read both of their books and follow both online blogs when I can. I now make my own silicade for myself and my wife and my 97 year old mother. But I am saddened to have noticed something of the disagreement you alluded to on Dr. Exley’s blog. He has endorsed the “natural” silica waters but has also explicitly said that the Silicade recipe which Dr. Crouse espouses – and which I use – is not demonstrated to work. I am glad to sense a certain professional polite-disagreement rather than animosity, but still unhappy to think that these two important gentlemen cannot find a way to mutually assure each other that the self-produced OSA/Silicade works. Of course I am asking here because I hope Dr. Crouse will seek a way to iron out this discouraging wrinkle. Personally I am not willing to sacrifice my children and grandchildren to the future toxicity of the immense amount of plastic I would be putting into the environment by purchasing 21 liters each week of Fiji or other “natural waters”. I will continue to use Silicade and hope for the best but would be so much more reassured if Dr. Exley could be brought “onboard” with this !
Hand-Crafted Silicade Made The Easy Way
My background is the art of synthetic chemistry as taught by Nobel Prize winners at Harvard University (e.g., E.J. Corey and R.B. Woodward). When I confirmed that by drinking Fiji water my mother’s short-term memory improved in spite of her Alzheimer’s diagnosis, I realized there was not enough Fiji water in the world for everyone with AD. In addition, shipping bottled water half-way around the world is unsustainable. Therefore, I developed an easy way to make Silicade, that has the same concentration of ortho silicic acid (i.e., OSA) as Fiji water, by neutralizing a special type of sodium silicate.
Some researchers make OSA rich water in their laboratory. Chris Exley said in his recent book “In my laboratory we prepare water that is high in dissolved silicon – silicic acid – for research purposes”. I prepared OSA using a liquid source of sodium silicate as described in the chemical literature and found it to “require sophisticated laboratory equipment” as mentioned by Chris Exley in his recent book.
Unlike liquids, powders can be measured with measuring spoons and therefore, sophisticated laboratory equipment is not required. I am lucky to live in the U.S. and not the U.K., as in the U.S. we have the PQ Corporation as a source of powdered sodium silicate. Powdered sodium silicate comes in several types, such as sodium orthosilicate and sodium metasilicate. I obtained various types of powdered sodium silicate made by the PQ Corporation, dissolved them in water, neutralized them with sodium bisulfate, and tested the resulting solution for the concentration of OSA using an OSA specific test. I found a way of using just two measuring spoons to make Silicade from one of PQ Corporation’s powdered sodium silicates. Silicade made only from this special powder has an OSA concentration that is identical to Fiji water. Other types of powdered sodium silicate, such as sodium metasilicate, do not result in sufficient OSA.
People who live in countries outside the U.S. can find companies, such as https://www.myus.com/ , that provide a temporary U.S. address through which this special type of sodium silicate powder can be forwarded to foreign addresses. Dennis N. Crouse – June 2023
