I bought this DC skimmer new less than a month ago. It's in new condition, works excellent, and is totally silent!! I do have the original box. Still has most of it's factory warranty left. Rated for tanks up to 320 gallons. Would probably handle a heavy bioload 200 gallon. I just realized that my tank is fighting zero nitrates and I don't need this new skimmer. I'll use my old ATB back up skimmer. $280 shipped or $250 local pick up (They're $349 new) It'll probably cost me $50 or more to ship.
