High Octane Power

Known for its strength and durability, FX Series sweeps the tank harder and faster to retain a greater amount of debris, which translates into cleaner water and less maintenance frequency.

Patented Smart Pump™ Technology

Pump Activity Monitoring

Smart Pump™ employs an electronic circuit board to continually monitor the pump. Impeller speed and force are constantly measured to ensure powerful output and energy efficiency.

Patented Smart Pump™ Technology

Auto Start / Self Priming

Smart Pump™ is also critical in evacuating any air that may build up in the system. Once every 12 hours, the filter will pause and allow any trapped air to escape, which maintains maximum filtration efficiency. Just add water and Smart Pump™ will prime in seconds.

Patented Smart Pump™ Technology

Whisper Quiet Operation

A cleverly designed unidirectional impeller incorporates less mechanical joints for reduced noise.

Multi-Stage Filtration

FX Series filters feature 2 inset red baskets for greater media capacity and flexibility. As with all Fluval filters, water flows through each media stage in proper order to ensure thorough cleaning. This process is more efficient and effective than some competitive filters, which force water through all stages in one pass.

Wide Media Selection

Discover Fluval’s complete range of authentic media solutions, offering higher quality, consistency and effectiveness to help support the overall health of your filter and fish.
