This is my last item I have laying around that I’m not using. It’s a Clearwater CW – 50 algae scrubber. It is the ready to run bundle from BulkReef Supply. Includes sicce pump with supply hose and flow valve. When I purchased it I think I paid over $400, will sell for $200. I used this scrubber for a year. I harvested good algae every two weeks. Extra equipment not in use reason for sale.
