Fluval FX4 High Performance Canister Filter

The Fluval FX4 circulates and filters 2650 litres of water an hour and has an astounding filter media capacity that produces the cleanest and healthiest results ever. Filtering media can easily be placed in a removable stack of media baskets which is at the heart of Fluval’s multi-stage filtration. The baskets are precision-engineered to eliminate water by-pass, making filtration more efficient. The baskets can hold a total of 3.9 litres of media and can be stacked in the precise combination of layers that will work best for your aquarium. Each one is lined with a foam insert for effective mechanical pre-filtering. Instant-release T-handles let you lift and separate the baskets quickly and easily, making routine maintenance simpler.

Includes Filtering Media
Even better news, Fluval FX4 comes with all the essential filtering media to provide complete and effective filtration immediately. No need to purchase additional media.

Enhanced Motor Technology
The FX4 is powered by a more efficient motor, which provides better performance while consuming 10% less electricity than its predecessor.

Intelligent Pump Technology
Fluval FX4 also features Smart Pump Technology, an advanced technological feature that continually monitors the pump, constantly measuring impeller speed and force to ensure powerful output and energy efficiency. It also manages the filter’s self-starting feature and evacuates air that may enter or build up within the filtration system. On a 12-hour cycle, the pump will pause and allow trapped air to escape, ensuring the best filtration efficiency at all times.
