The patented easy-to-use Supreme Skilter 400™ is a unique combination of a protein skimmer and an aerating power filter for use in fresh & saltwater aquariums. It is an effective primary or supplemental filter along with its operation as a skimmer for 30 to 100 gallon aquariums. It is a total system, combining chemical, mechanical, and biological filtration techniques. The protein skimmer portion of the system will handle aquariums up to 125 gallons, provided additional mechanical filtration is present. The advanced venturi-type protein skimmer reflects the latest technology. Air is injected into the water creating millions of very fine bubbles. Potentially dangerous protein compounds and toxins adhere to the bubbles creating a froth. This frothy waste continues to accumulate until it pushes its way up into the collection tray. The saltwater that is filtered by the ruggedly built Skilter 400™ is virtually saturated with oxygen. The increased amount of oxygen that re-enters the aquarium water helps provide a better environment for fish and invertebrates alike. This powerful system pumps up to 400 gallons pet hour flow. Just hang it on the back of the aquarium, just like a standard power filter. Designed to be self-starting an maintenance-free. Shipping-Weight: 6.5 lbs |
