Introducing the Fluval FX4 External Filter, a powerhouse canister filter that promises high performance and reliability for your aquarium. This compact filtration system is the ideal choice for tanks up to 250 US gallons, bridging the gap between the Fluval 406 and the FX6 canister filter.

With its advanced microchip technology, the FX4's Smart Pump™ continuously monitors and optimizes pump performance, ensuring efficient water filtration. The self-starting feature makes set-up a breeze - just add water, plug in, and let the Smart Pump™ take over.

One of the standout features of the FX4 is its easy water change system. Say goodbye to heavy buckets as you simply attach the hosing to the output, and the Smart Pump™ does the rest. Trapped air is automatically evacuated every 12 hours, maximizing the filter's efficiency.

The FX4 is designed with convenience in mind. The removable stackable media baskets eliminate water bypass, holding a generous 1 gallon of media that includes mechanical, chemical, and biological filter media. The Aqua-Stop valves with the leak-proof Click-Fit attachment system ensure hassle-free installation and rotation, thanks to their 45-degree angle positioning.
