I have a fluval fx5 canister filter forsale. This thing is a monster, and I'm gonna downsize a little bit. All seals and most plastic pieces have just been replaced. It does 924 Us gallons an hour, has 3 media baskets (good for liverock) And comes with a few water polish pads and carbon. Askin 150$ Here is a link to a new one on amazon.
