This External Canister filter is highly efficient, with a large capacity canister, and also each comes with a built in UV Steriliser too, which comes with its own separate switch control.
The water inlet and outlet are both intergrated in the valve control, making this super easy for maintenance, running with a high quality pump, that is also quiet whilst running - a must have! The rubber feet on the bottom also help to reduce any noise vibrations as well, so can be placed inside aquarium cabinets easily.
These canisters are suitable for both marine or freshwater systems, and range from a 100l tank through to a 650l full system.
