I'm in Planted School.
We have settled on the play sand but my next issue is about air pumps. We have an air pump running with two 3" airstones in our 46g{which is river rock gravel}. For our 75g with sand I don't think we could bury airstones in sand without them just uncovering themselves.....Do you need an air pump at all? I'm confused about how to use one with sand as substrate.
