Black Aquarium Filter for Aquarium

This black biochemical sponge filter combines mechanical and biological filtration in one compact unit powered by a standard aquarium air pump. The sponge material provides excellent surface area for beneficial bacteria colonies that process ammonia and nitrite, while simultaneously mechanically trapping waste particles before they enter the water column. The black housing blends discreetly into most aquascape layouts.
