Fluval FX4 Canister Filter for Aquariums
About this item
- Enhanced Performance: Multi-stage filter pumps out 700 US Gal (2,650 L) of water per hour. Patented Smart Pump technology uses advanced microchip monitoring to continuously optimize pump performance.
- Self-Starting: Just add water and plug it in—Smart Pump technology takes over automatically. Trapped air is auto-evacuated every 12 hours to maintain peak efficiency.
- Multi-functional Utility Valve: A drain at the base allows easy emptying of the canister and seamless water changes by draining and refilling directly. The lid includes hose clips for neat storage when not in use.
- 4-Stage Filtration: Includes four removable filter baskets to prevent water bypass. These baskets hold up to 1 US Gal (3.9 L) of mechanical, chemical, and biological media. Customize the filtration setup to best suit your aquarium needs.
- Compact and Quiet Design: The FX4 canister filter is 16.5″ (42 cm) tall and fits under most aquariums. A unidirectional impeller with fewer joints reduces noise, and rubber feet minimize vibration while increasing stability.
