HIGH PERFORMANCE 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.


HIGH CAPACITY POWER, LOW MAINTENANCE
Known for its strength and durability, the FX series sweeps the tank harder and faster, while picking up a greater amount of debris, which ultimately translates into less maintenance frequency.

MULTI-STAGE FILTRATION
The lift-out stack of media baskets is at the heart of Fluval multi-stage filtration. These large capacity baskets enable you to stack filtration media in the precise combination of layers that will work best for your aquarium.
The latest generation of FX filters incorporates 2 additional trays for even greater media capacity and flexibility.
