Filtering at the highest level. Fluval's FX External Filters feature performance-optimized patented Smart Pump technology, complex multi-stage filtration, an integrated high-performance water exchange system, and a basket stack insert arrangement for greater filter media capacity. It is the ideal choice for aquarists with aquariums up to 1000 litres of water. Faster cleaning. Known for its strength and durability, the FX6 filter filters an impressive 3500 l/h in aquariums with up to 1500 litres of water. This type of power cleans the pool more and faster. A larger amount of impurities is absorbed, which leads to a lower maintenance frequency. The FX series has a multifunctional drain valve at the bottom of the filter container. Thanks to this valve, the water can drain from the filter tank, leakage-free water changes can be carried out and the water can be refilled directly (all this without changing the structure of your tank and without disturbing the aquarium inhabitants).
