The Ista Surface Skimmer has been designed to draw water from the surface of the aquarium, eliminating undesirable films caused by floating protein and organisms. By ensuring the surface of your aquarium water is crystal clear, you are in turn improving the exchange of oxygen and the ability of light to penetrate the surface.
Since this Surface Skimmer contains no metal parts, marine aquariums that do not employ a surface overflow will substantially benefit from its implementation! Also its patented self-floating inlet design lets water in from all directions, and automatically adjusts itself according to the level of the water. For your convenience, the Ista Surface Skimmer is very easy to install, fitting all canister filters, and is just as easy to maintain!
