I think I am going to try a tank with no substrate. Probably a 120 gallon. I will still grow plants like Anubias, Ferns, Mosses etc.... My biggest concern is stability of the bio.
Is anybody doing this? I usually like to have a Penguin 400 biowheel and a Canister trying to get about 400 gph between the two. I recognize the filters will have to pick up the slack for the lack of bacteria in the substrate, but is there anything else I need to consider? I have this worry that the water parameters will be more fragile.
