Our high-performance REEF-SPEC^® Skimmers feature a combination of PSK pumps with proportionally sized venturi, bubble diffusor and reaction body that optimizes air-water contact time for steady waste removal.   Designed with hobbyists needs in mind, the REEFER™ Skimmers are really quiet thanks to rubber connectors which dampen the vibrations as well as a robust air silencer. With features like the FoamView™ window, built-in neck cleaner and extra-long valved waste tube, we guarantee an enhanced home reef filtration experience.
