Fluval FX4 Canister Filter  £247.99

Recognized as the “workhorse of canisters” for their legendary strength and durability, high output FX Series filters sweep the tank harder and faster to retain a greater amount of debris. Combining patented SMART PUMP™ performance-optimizing technology with auto start/stop operation and intricate multi-stage cleaning featuring an expansive basket-in-basket media tray design, FX owners will spend more time enjoying their aquarium, and less time maintaining it.
