The Fluval FX6 is the largest, highest-capacity canister in Fluval’s FX range, made for freshwater and saltwater aquariums up to 1500 litres. It moves a large volume of water to pick up more debris, and its big media baskets give beneficial bacteria plenty of room to grow.

Smart Pump technology monitors and adjusts the pump as it runs. The filter is self-starting, so you just add water and plug it in, and it releases trapped air every 12 hours to keep it running efficiently. It also comes with all the filter media you need to get started.
