allpondsolutions 2000EF+ Aquarium External Fish Tank Water Filter with 9w UV Steriliser for Coldwater, Tropical or Marine Aquariums, for Tanks Up to 1000 Litres - Includes Filter Media, Full Kit

AllPondSolutions 2000EF+ External Filter. These filters work on the same principle as internal powerhead filters, but are positioned outside the tank and draw water into the filter through an inlet tube and return the water via an outlet tube. The outlet tube is fitted with a spray bar to increase aeration within your tank. These type of external filters avoid the need for an unsightly filter inside the tank and the media capacity is much larger than internal filters and they are therefore suitable for much larger tanks. Suitable for aquariums up to 1000L
