external filter

FX Series filters feature 2 inset red baskets for greater media capacity and flexibility. As with all Fluval filters, water flows through each media stage in proper order to ensure thorough cleaning. This process is more efficient and effective than some competitive filters, which force water through all stages in one pass.

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.
