So im looking for max filtration, I have been doing lots of research and an getting confused on what is what now. I have a 180 gal tank with 5 6" Oscars and a 1 foot long RTC and a Foot long RTCXTSN now in know that they will need a bigger home and that will happen in a years time but for know i need a new filter. right now i have a hang on the back 100gal filter i think its an empor or penguin. and a cpr overflow box with two outlits that go in to a home made sump that houses bio balls filter pads and carbon. i want to add a canister filter because of the growing fish, which are the easyest to clean, most affortable to replace media, and works the best. thanks
