Hi folks, I am new to the forum. I have had freshwater tanks off and on for probably 20 years (and my grandfather used to breed fish and sell them to the local pet stores...) but I am still far from an expert! I am looking at setting up a tank my kitchen (please tell me if this is a crazy idea!) and I am looking to upgrade to a larger tank than what I have had in the past... I don't want to obstruct my walk way too much. The guy at the store suggested using a canister filter so I could get the tank closer to the wall. I never used a canister filter and I thought they were for salt water. Have any of you used a canister with your freshwater tanks? How do these work? Thanks!
