A compact multi filter from Aquarium Systems with optional water surface skimming. The Cobra is so named because of it’s articulating output which can twist and turn to direct flow in just about any direction from the main body, and the main outlet also features additional directivity and flow control at the very top. Perhaps the most exciting feature for marine aquarists is the included and removable surface skimming ‘snorkel’ which allows the Cobra to filter the wastes that build up on the surface of the water, a frequent problem in nano reefs using only a little power filter.
