These effective filters draw water evenly through the entire gravel bed. The 1" -diameter lift tubes and tube collars have guards to keep fish from entering the tube or getting under the plate. Unused collars are capped. The filters work in both freshwater and saltwater standard aquariums. Each filter comes with one filter cartridge per lift tube and instructions. An air pump, required, is available separately.
