Fluval FX2 High Performance Canister Aquarium Filter - Multi-Stage Filtration, Built-in Powered Water Change System, and Basket-in-Basket Tray Design

Recognized as the "workhorse of canisters" for their legendary strength and durability, high-output FX Series filters sweep the tank harder and faster to retain a greater amount of debris. Combining patented SMART PUMP performance-optimizing technology with auto start/stop operation and intricate multi-stage cleaning featuring an expansive basket-in-basket media tray design, FX owners will spend more time enjoying their aquarium, and less time maintaining it.

• Enhanced Performance: Multi-stage filter pumps out 475 US Gal (1,800 L) of water per hour, with the patented Smart Pump advanced microchip technology continuously monitoring and optimizing pump performance.
• Self-Starting: Just add water, plug in and Smart Pump technology will take over. Any trapped air is auto-evacuated every 12 hours to ensure maximum efficiency.
• Multi-functional Utility Valve: Drain at the base makes it possible to empty the canister and perform seamless water changes by draining and refilling water directly from it. Convenient lid-mounted hosing clips offer 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 media: mechanical, chemical, and biological. These baskets enable you to stack in the precise combination that will work best for your aquarium.
• Compact and Quiet Design: FX2 canister filter is 16.5" (42 cm) tall, is 15% smaller than the FX4, and fits under most aquariums. Unidirectional impeller has fewer mechanical joints for reduced noise. Rubber feet reduce vibration and add stability.
