Fluval Foam prefilter

Filtration at the highest level. The FX external filter from Fluval features performance-optimized, patented Smart Pump technology, complex multi-stage filtration, an integrated powerful water change system, and a basket stacking arrangement for greater filter media capacity. The brand new FX4 filter builds on the powerful FX platform and is the compact "little brother" of the FX6 filter. It is the ideal choice for aquarists with aquariums up to 1000 liters of water.

Faster cleaning. The FX6 filter is known for its strength and durability, filtering an impressive 3500 l/h in aquariums of up to 1500 liters of water. This level of performance cleans the tank more thoroughly and quickly. A larger amount of impurities is captured, resulting in less frequent maintenance.

The FX series features a multifunctional drain valve at the bottom of the filter container. Thanks to this valve, water can drain from the filter container, leak-free water changes can be performed, and water can be refilled directly without changing the setup of your tank and without disturbing the aquarium inhabitants.
