Simplicity DC Protein Skimmers - The Simplicity Protein Skimmer line has turned the Protein skimmer market on it ear! It has replaced more than a handful of very inexpensive skimmers with a Hi-End product that is hard to compete with! At Aquatic Warehouse we have sold hundreds of these because they work remarkably better than anything close to their price range. Why spend more when Simplicity is only a click away wit Aquatic Warehouse?
