Regarding filters and making Silicade, you have to use the Brita filter for making the Silicade. This step can not be eliminated as there are impurities in the ingredients which need to be removed. The Brita filter is unique as it filters out aluminum but does not filter out the OSA....
I have an idea and i need your opinion of it
If the OSA remove harming aluminum from body So i guess it will remove it from the silicade water (unless the amount of harming aluminum in the impurities is so much) so in that case we can use regular carbon filter to get rid of the other impurities and i think we will not need to add baking soda to water and we will only have to add little sodium bisulfate to reach the ph 7 of water .
So what do you think about this ?
My husband Dennis N Crouse developed this recipe. What you are proposing is UNSAFE. There is a reason for each step in this procedure and each step needs to be implemented. Here is information from the recipe.
"Why This Recipe Works
The goal of this recipe for orthosilicic acid (OSA) in drinking water is to use an easily measured solid silica powder and an acidic microprill that are commercially available online and shipped to anyone, not just chemical laboratories. Both of these chemicals are high purity (e.g. 99.5%).
· Solubilize sodium silicate: Boiling powdered sodium silicate for 30 seconds in an eighth of a cup of tap water keeps the pH high enough (e.g. pH = 13) to solubilize silicate434-436.
· Neutralize to form OSA and prevent polymerization: In order to form OSA and other silica species in equilibrium with OSA489 and to prevent OSA polymerization435-437, immediately dilute the basic (e.g. pH=13) OSA solution to a gallon with tap water and then immediately render the solution non-hazardous by acidifying the solution to pH 4 to 5 with the solid acid sodium bisulfate. A 1.29mM OSA solution is well below OSA’s saturation level in water (e.g. 2-3mM) but requires 7 days to fully stabilize rising from 108ppm immediately after preparation to 124ppm174. Polymerization of OSA has been observed at neutral pH only well above OSA’s 200ppm saturation level435-437.
· Remove Aluminum: For optimal aluminum removal acidify the OSA solution with sodium bisulfate to pH 4.0 to 5.0 and then filter through a Brita pitcher style filter (OB03)174. A significant portion (e.g. 98.5%) of the labile aluminum introduced in tap water is removed174,175. This Brita filter is a combined activated carbon and weak cation exchange resin that removes cations like aluminum but does not remove OSA174. If the tap water used for Silicade is between pH 6.5 to 8.5, as per EPA’s secondary drinking water standard, then after acidification, filtration, and bicarbonate addition Silicade will be pH 6.5.
· Optionally add Calcium and/or Magnesium: Have your tap water checked and if it is low in calcium and/or magnesium, add supplemental calcium and/or magnesium to Silicade. The Brita filter reduces calcium and magnesium in Quabbin tap water by one half175. Drinking water with calcium at levels of 80mg and magnesium at levels of 20 ppm has been found to be optimal for good health438. This may be due to calcium and magnesium competing with aluminum for absorption by the gut433. Calcium catalyzes the polymerization of OSA but only at pH greater than 818,19. Silicade + Ca is pH 6.6 and at this pH OSA in Silicade + Ca is primarily a non-polymeric monomer174,439. "
