Fluval FX6 Canister Filter – Generation 2

Fluval FX6 Canister Filter – High Performance Canister Filter

For fresh and saltwater aquariums up to 1500 L (400 US Gal)

Building on the hugely successful FX5, FX6 is Fluval’s next generation filter workhorse, with all the power and reliability that Fluval FX filters are known for–plus more. FX6 has an amazing range of advanced features, all designed to make fishkeeping so much easier and more convenient.

FX6 is a super capacity yet compact canister filter that pumps out 3500 liters (925 US Gallons) of water an hour and has an astounding media capacity that produces cleaner and healthier results than most competitive filters.

The FX6 draws in water and suspeded debris through its clog-proof intake strainer and sends it through a three-level foam pre-filter which traps most particulate matter. It proceeds to flow through multiple levels of custom media configurations to be processed and cleaned. As the powerful pump returns water to the aquarium, the flared design of the adjustable output nozzle disburses it in multiple directions, creating currents that help direct waste towards the intake for filtering. This intricate process results in a continuous flow of filtered water.

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.

Smart-Pump Technology
Fluval FX6 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. Fluval FX6 Smart Pump Technology is the key to providing optimal filter performance. This self-primimg system offers plug-in-and-start convenience. Smart Pump employs an electronic circuit board to continually monitor the pump.
