| | Re: ADA Aquasoil Powder in 75 Gallon Aquarium
ADA Aquasoil in powder form was not intended to be the sole substrate in a large aquarium - 2-3 inches deep. You would be wasting a lot of money to do so, but I don't know what bad effects it would have. Flourite Sand is a different substrate material. I once used in as the only substrate in a 10 gallon tank, and it worked with no problems. I liked its appearance, but never tried it again in bigger tanks.
When you place fine particle substrate material on top of coarser material the fine stuff eventually moves to the bottom of the substrate, leaving only the coarser material visible. The manufacturer of Eco Complete even claims this as an advantage of using that substrate - the fines naturally go to the bottom where they are useful.
