Fluval Underwater Filters provide easy, convenient filtration, and have the capacity to independently filter aquariums up to 57 U.S. gal. (215 L) capacity. The Fluval "Plus" underwater filters feature a clogging indicator, allowing visual indication of when maintenance is required, and a cartridge design which prolongs service intervals.

Internal filter systems, such as the Fluval "Plus" underwater units, offer the following application possibilities:
  1. Vertical or horizontal filter placement.
  2. Can be used to create waterfalls in turtle and reptile tanks.
  3. Additional filtration for many different aquarium set-ups.
  4. Useful for creating extra currents in reef tanks.
  5. Driving Ultra-Violet Sterilizers (reduction of particulate matter, increasing U.V efficiency).
  6. Providing filtration when external filters cannot be installed.
