Skilter 250 gph Power Filter, up to 55 gals

This Skilter 250 gph aquarium power filter has provides three stages of filtration as it passes through the Supreme Bio-Matrix cartridge.

1. It’s mechanically filtered by the dense polyester filter material.
2. It then passes through an activated carbon medium that is specially designed to be an effective chemical filter.
3. Finally, the entire cartridge, surrounded by its unique clam-shell style frame, acts as an efficient biological filter.

The snap-together cartridge is easy to replace and allows for either partial or total change of the filter media. This assures uninterrupted bacterial filtration.

A Supreme Skilter filter integrates a mechanical power filter with a protein skimmer in a single device, although many contemporary aquarists view it as outdated and less effective compared to specialized skimmers. The primary function of a Skilter filter is to offer dual filtration by drawing water through a filter box that accommodates mechanical or chemical media while simultaneously introducing air to facilitate foam fractionation in the protein skimmer. Additionally, it excels in waste removal, as the venturi impeller generates fine bubbles that capture dissolved organic waste, directing it into a collection cup. Furthermore, the Skilter filter enhances aeration, ensuring substantial oxygenation and gas exchange within the aquarium water.
