I bought an AC 110 for my 120 but the tank is sitting too close to the wall to get it on the back. Just by a hair too. :sad: Anyway, instead of trying to move my tank I though about selling it to my sister who is going to soon put a couple of Sevs in her 55G. Would that be overkill or should I just return it and get a smaller one for her. I'm just going to get another canister for myself.
