Fluval Aquarium FX4 External Canister Filter

European ingenuity and innovation have fuelled the next generation of FX canister filters, which feature patented smart pump performance-optimising technology, intricate multi-stage filtration and a built-in powered water change system. As always, you can expect FX’s legendary mix of power and efficiency that lets you spend more time enjoying your aquarium and less time maintaining it.

Building on the mighty FX platform is the all new FX4, a compact “little brother” to the FX6. Known for its strength and durability, FX6 outputs 3500 L/h in aquariums up to 1500L. Capable of outputting 2650 L/h, the FX4 bridges the gap between the Fluval 406 and the FX6 canister, making it an ideal choice for consumers with aquariums up to 1000L.  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.
