Lee's Protein Skimmer Small #17100

Lee's Counter Current Protein Skimmers help prevent toxic tank syndrome by removing proteins and other organics before they turn into nitrogen compounds or other toxins that may be harmful to aquarium inhabitants. Through ADSORPTION, protein and other organic compounds in the water form a coating around bubbles as they rise to the top. The resulting foam floods over the top of the foam riser tube and is captured in the collection cup before it can re-enter the aquarium. Easily adjusted, low maintenance protein skimmers come pre-assembled, with 2-way plastic valves and hanger included. For use in saltwater aquariums and reef tanks up to 30 gallons. Skimmer is 12-1/16" long. Shipping weight: 1 lb.
