You may be right. May be mine is not a true canister filter but it's not a sump in bucket. In sump, you have compartments whereas mine don't have any. And the pump resting on the bottom, continuously sucking the water, forcing the water pass through the media. This creats pressurized ckeancle. So may be mine is part canister.
Anyway, thanks for the info. About joeyJo canister filter, may be it's hard to run.
Thanka
