Selling my Reef Octopus DDNW-150-6530. Used for about a year. Reason for selling is because I have decomm my Marine Tank that is using the Protein skimmer. This is a powerful skimmer for up to 1300L tank. It comes with 2 needle wheels 2000/l OTP-2000 pump with 900l/hr of air.

I am throwing in the feeder pump, Rio HF-04, which is used to draw water into the skimmer for best performance at low power consumption. I am selling this skimmer at $200 .
