Fluval FX4

Fluval FX4
The Fluval FX4 is based on the high performance FX6 canister filter with the same outstanding features designed to make aquarium fishkeeping easier and more convenient!
This super capacity yet compact canister filter processes and circulates 1700 litres (375 gallons) of water every hour and has an astounding media capacity that produces cleaner and healthier results. The Fx4 bridges the gap between Fluval's famous 406 and FX6 external filters as the FX4 is suitable for aquarium's up to 1000L.
Filtering material can easily be placed in a removable stack of media baskets which is at the heart of Fluval's multistage filtration. The baskets are precision-engineered to eliminate water by-pass, making filtration more efficient.
The baskets can hold a total of 5.9 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.
Fluval FX4 also features Smart Pump Technology, which provides optimal filter performance. This advanced technological feature employs an electronic circuit board that continually monitors the pump. Impeller speed and force are constantly measured 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.
