Well after reading review after review I have decided to get a Eheim classic canister for my new aquarium. Just one question though, do I need the 2215 or 2217. My tank is a 45g, 36in x 13in x 24in, I plan on it being a non-planted community with tetras/danios. This needs to be a stand alone filter also, no hob
or power head used as extra.
Any help is appreciated.
