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:
- Vertical or horizontal filter placement.
- Can be used to create waterfalls in turtle and reptile tanks.
- Additional filtration for many different aquarium set-ups.
- Useful for creating extra currents in reef tanks.
- Driving Ultra-Violet Sterilizers (reduction of particulate matter, increasing U.V efficiency).
- Providing filtration when external filters cannot be installed.
