Someone told us that i shouldn't use silica sand if i've got a planted tank. I want to stick plants in there too so does this mean i cant use silica sand?
its nonsense, the problem is that its an un-fertilised substrate, so the plants dont really benefit from it (but the same is true of gravel as well)
one of my most successful planted tanks has 1" of potting soil and 1" of silica sand, and the tank is completely full of plants (actually need to weed it out something chronic )
