FLUVAL FX4 Canister Filter

FLUVAL FX4 Canister Filter – High-Performance Filtration for Large Aquariums

The FLUVAL FX4 Canister Filter is a powerful, high-performance external filtration system designed for aquariums up to 1000 litres (250 US gallons). Positioned as the compact "little brother" to the renowned FX6, the FX4 bridges the gap between traditional canister filters and premium large-capacity filtration systems. Designed and manufactured in Italy, it delivers exceptional water quality for both freshwater and saltwater aquariums.

Built with European engineering and innovation, the FX4 features advanced SMART PUMP™ technology, which continuously monitors and optimises pump performance for maximum efficiency. The intelligent microchip automatically manages filter operation, ensuring reliable performance while reducing maintenance requirements. With a powerful flow rate of 2650 litres per hour (700 US gallons per hour), the FX4 effectively removes waste, debris and impurities to maintain crystal-clear aquarium water.

The self-starting design makes setup simple. Just add water, plug the unit in and the SMART PUMP™ system takes over. The filter automatically evacuates trapped air every 12 hours, helping maintain peak filtration efficiency and uninterrupted water flow.
