The Coralife Super Skimmer is a high-performance foam fractionator designed with a patented needle-wheel impeller and aspirating venturi. An improved energy saving pump increases the performance of the skimmer without increasing power demand.The needle-wheel system creates a spiraling vortex of water and micro bubbles inside the reaction chamber where the bubbles attract fine proteins and organic compounds and deposit them in the collection cup. The result is a clean and healthy aquarium environment.
