I'm selling my Reef Octopus protein skimmer that I bought a year ago for $606.00 It has a brand new controller and is still under warranty. I love this skimmer and it worked great on my 180g with a 70g sump, not so well on my 370g with a 130g sump. The only reason I am selling it is because I got a new tank and upgraded to the biggest model. It was used for less than a year.
