wait! i'm confused! i thought the canister filter was like the whisper submersable filter. (like the entire filter goes into the tank pretty much) am i mistaken?
Canister filters are like cans that go on the floor near the tank and have input/output hoses. They usually have a large compartment for variable media of your choice, or multiple compartments, that they cycle the water through.
The hoses go back into the tank. One will provide water back into the tank via a jet similar to a power head or spray bar, the other will take water out similar to the inlet of a HOB filter.
well i was just at this fish action and they were actioning off a canister that was up to 1100 gallons. it was sold for like, i think it was $35 and i wanted to bid, but i thought that was WAY too much filtration for a 75 gal. was i right to pass on this oportunity?
