Fluval FX4 Canister Aquarium Filter System
About this item
- Enhanced Performance: Multi-stage filter pumps out 700 US Gal (2,650 L) of water per hour. Patented Smart Pump advanced microchip technology continuously monitors and optimizes pump performance.
- Self-Starting: Just add water and plug in—Smart Pump technology takes over. Any trapped air is automatically evacuated every 12 hours to ensure maximum efficiency.
- Multi-functional Utility Valve: Base drain allows emptying of the canister and seamless water changes by draining and refilling directly from the filter. Lid-mounted hosing clips provide clean storage when not in use.
- 4-Stage Filtration: Four removable filter baskets eliminate water bypass and hold up to 1 US Gal (3.9 L) of mechanical, chemical, and biological media. Baskets allow you to stack the optimal media combination for your aquarium.
- Compact and Quiet Design: The FX4 canister filter stands 16.5″ (42 cm) tall and fits easily under most aquariums. Unidirectional impeller has fewer mechanical joints for reduced noise. Rubber feet help reduce vibration and improve stability.
