I personally dont like canister filters. I'd rather oversize a hang on back filter. Maybe something like this. Since you said you want to go FOWLR. Built in UV sterilizer, and get the 40gal tank version.Thank you! Right now we just have an Aqueon QuietFlow 30 but I’m already considering upgrading to a canister filter?
It is a small tank. We’ve been using poly filter to help strip the extra ammonia as well.
