I bought some 40% water glass to start dosing silicates in an attempt to battle Amphidinium dinos. 80g tank and plan is to dose 2ml per day. Problem is it instantly precipitates when it hits the water and doesn’t seem to dissolve at all. I then read to mix it into some rodi water first, but having the same issue. It’s just a cloud of precipitated particles floating around in the water that eventually all settle on the bottom and doesn’t dissolve?
