Thanks for that—I actually already have this in my Amazon cart (along with Monosodium Phosphate [NaH2PO4] 98+% AR Grade Powder 8 Oz in a Bottle
https://a.co/d/45QWmq7 and Dawn Scientific Potassium Nitrate 1lb
https://a.co/d/idylIii) but wasn’t sure what would be a suggested dose per 10 gallons. I gather it’s about 22X stronger than Brightwell’s SpongExcel, but I’m not feeding sponges. ;)
My recommended dose for ordinary dosing is below. You might up that in a Dino situation.
Copied from my silica article:
Based on my dosing experience, aquarists are probably safe dosing the equivalent of 1 ppm SiO2 once every 1-2 weeks. That is based on the fact that my tank used that much in less than 4 days without having any sort of “bad” reaction. Of course, there’s nothing wrong with starting at a tenth of that and ramping up. And, of course, if you do get too much in the way of diatoms, just back off on the dosing. I presume that all that I added to my tank went into various organisms that us it (sponges, diatoms, etc), but perhaps I have more sponges than other aquarists, and diatoms consequently may be more of a concern in some tanks than in mine.
Here’s how to determine dosing amounts. I’ll assume that you want 1 ppm SiO2) dosing, and you can scale from there. If the concentration of the supplement is 29% silica by weight (41° Baume), then it is 290,000 ppm silica. To get to 1 ppm silica, you then need to dilute by 290,000 fold. If you add 1.3 grams of this supplement (0.96 mL) to a tank with 100 gallons (378,500 mL), then the final concentration will be about 1 ppm SiO2.
I’d disperse the concentrated silicate solution into some fresh water before adding it to the tank, and then add it to a high flow area. Because the pH is high, you likely will see some cloudiness that is mostly magnesium hydroxide. The magnesium hydroxide will dissolve without a problem, but to be safe, add the supplement in a high flow area.
