I have an Reef Dynamics XRC1000.5 Protein skimmer for sale. External operation, 4 Eheim 1262 needlewheel pumps included. This model originally sold for $3999. I don't know the capacity but I know it handled my 500G system with ease. I also have part that you can add a 5th needlewheel pump. Total dimensions are 42" tall, 13" cylinder dimension (24" overall). There is one crack in acrylic that caused some seepage when filled so I ran this unit over my sump with no problem. Sell $600 OBO, pickup only in Cary, IL. See video below. Mike
