![]() I have a few of my tanks with canister filtres and am toying with the idea of taking out all of the sponges, and miscellaneous media in the different trays and filling the trays with coral and rock fragments to act as the filtre.
I am looking at this cuz I am still struggling with high Nitrates. Rumour is the sponges are a major cause of this. Looking for some advice and opinions thanks in advance Neal
