High Performance Canister Filtration 

European ingenuity and innovation have fueled the next-generation of FX canister filters, which feature patented SMART PUMP performance-optimizing technology, intricate multi-stage filtration, a built-in powered water change system and basket-in-basket tray design offering greater media capacity. As always, you can expect FX's legendary mix of power and efficiency that lets you spend more time enjoying your tank, and less time maintaining it.

Known for its strength and durability, the FX6 outputs an impressive 925 GPH in aquariums up to 400 gallons. That kind of power sweeps the tank harder and faster, while picking up a greater amount of debris, which ultimately translates into less maintenance frequency.

Building on the mighty FX platform is the all-new FX4, a compact "little brother" to the FX6. Capable of outputting 700 GPH, FX4 bridges the gap between the Fluval 406 and the FX6 canister, making it an ideal choice for consumers with aquariums up to 250 gallons.

The latest generation of FX6 incorporates 2 additional trays for even greater media capacity and flexibility. With FX, the water path involves a sequential process that makes it cleaner and cleaner as it travels through each stage of filtration. This concept is far more efficient and effective than other canisters that force water through all filtration stages in one shot.The FX series features a multi-functional utility valve drain at its base, making it possible to empty the canister and perform seamless water changes by draining and refilling water directly from it (and all without disturbing your setup or tank inhabitants). As an added bonus, convenient hosing clips, located on the filter lid, allows for simple storage of the hosing when not in use.
