I am a newbie (ish). I have had multiple tanks for a few years. When I set up my 55 gal I was given the ABI Nexx filter with one extension, which I do not love. I have a new 75 gal tank that I am looking to set up. I have never bought a canister filter. I am looking into fluval 406. I am not set on it. Does anyone have pros/cons or opinions on better options? Thanks in advance!
