So I'm look for a canister filter for a 125 gallon SA/CA cichlid tank. At first glance at chain stores I can either get 100 gallon capacity filter (not enough by itself) or a 400 gallon filter... Now the 400 gallon wouldn't be a problem except for the cost. At $330 it's going to cost me as much as the tank, stand, light and hood combined. Not saying I'm trying to go cheap, but does anyone have any other suggestions?
