NPK RAW Silica | 10 lb | 45% Silicon Dioxide From Diatomite Size:10 lb On high it moves 6RAW Silica Is The Dry One On A Shelf Of Liquid Silicates Almost every other silica sold for growing is a liquid potassium silicate. Those lift reservoir pH sharply, have to go into the tank before anything else, and will gel if they meet concentrated calcium. NPK RAW Silica is none of that. It is a dry powder whose silicon dioxide comes from diatomite, which NPK put forward as an acceptable alternate to potassium silicate. Because it is a natural
