so after months of looking.. i finally bought a 210 gallon tank. I was wondering if anyone had any suggestions on filtration for it? its 7x2x2. Its an upgrade from my 55 gallon. Is there any certain type of filter which would be better than the other? Right now I have two hang-on filters. I was leaning towards a canister. I have an Oscar, Pacu, Irridecent Shark, 3 Balas, Angel and 2 over grown feeder goldfish. Any suggestions would help. Thanking You in advance.
