External Filters

External aquarium filters sit next to or below an aquarium. Water is drawn in to the filter through an input tube from the aquarium into the canister for filtration and the cleansed water is then pumped back into the aquarium. An integral water pump is used to manage the movement of water into and out of the aquarium.

An external fish tank filter can be hidden away from view and is ideal for large or heavily stocked aquariums. External filters are easy to work with as they may be connected under or near the tank and are easy to adjust. They also keep fish stress to a minimum due to the fact that you don’t have to interfere with the tank to perform filter maintenance. 

Here at Homeleigh you can browse our huge range of external aquarium filters online, but if you don't see the product you require, please call our aquatic team on 01566 771878 as we may have it in store.
