I've got an AquaClear 110 on our 56 gallon tank. It came with sponge for the bottom, carbon for the middle and bio for the top. I took the carbon out after about 3 months. I bought another sponge for the middle but it seams to be too thick to keep the bio media down into the water enough.
What filter media is everyone with that filter using?
Thanks!
Paul
