Aquamaxx Water Cyclone Protein Skimmer The JNS WS-1 protein skimmer features an incredibly responsive collection cup and an amazingly powerful submersible pump. It is rated up to 65 gallons in a design thin and light enough to be placed on a nano aquarium, all-in-one style aquarium or other small saltwater aquarium.The JNS WS-1 protein skimmer removes organic waste from aquarium water. It creates a strong mix of small air bubbles and turbulent water movement to force protein, waste and other materials into a collection cup for easy removal. The new Conical diffusers help to reduce turbulence in the reaction chamber and achieve more-stable, laminar flow to maximize performance.
