Thanks! So potassium silicate liquid is already broken down into the two components when you use it? Then why does it precipitate out a bucket of nutes where MSA doesn't?
From Dyna-Gro's FAQ's
"How do I mix Pro-Tekt with Nutrients and Additives.
Pro-TeKt is introduced first into the mixing tank/container then add ¾ of the intended volume of water. Finally, add the other nutrients and top off with the remaining volume of water. Because a very high pH is required to keep Pro-TeKt concentrate in solution, it is important to fully dilute it before adding other Dyna-Gro nutrient solutions which have low pH. Mixing the two concentrates without first diluting them will turn Pro-TeKt into a lump of silica gel!"
Personally I fill my 1 gal container and forcefully inject the silica additive via syringe and blunt needle 1st. Then I add my other products afterwards in the same manor. I've never had an issue with precipitate or gelling. As long as you're not mixing 2 concentrates before adding water, it shouldn't be an issue. Most precipitation problems in nutrient solutions are from mixing high concentrations of Sulfates and Phosphates with Calcium. That's why you see a lot of Part A and Part B solutions. You'll typically see the Calcium in Part A, and the Phosphates and Sulfates in Part B. At more diluted concentrations, they don't precipitate out, but if they put both in the same bottle as a concentrated fertilizer, boom. That's why you can't make a concentrated stock solution from Mega Crop. Their site says you can somewhere in the FAQ's, but that's BS. Every time I tried it I got clumpy shit at the bottom after a day. I wasted over 500g of powder on that failed expiriment.
