Two Little Fishies PhosBan Media Reactor 150

Two Little Fishies PhosBan Media Reactor 150

The Two Little Fishies PhosBan Media Reactor 150 up-flow design forces all the water to pass through the media in one pass, thereby maximizing contact time between the media and the water and significantly improving the effectiveness of the filter media. Works great for various media, including carbon, GFO, and bio-pellets. Its low profile and built-in hanging bracket make it ideal for a variety of installation applications.

  • Improves efficiency of filter media
  • Compatible with carbon, GFO, bio-pellets, and other types of media
  • Easy to set up and use

Improves Efficiency of Filter Media

By driving water from the base upwards, the reactor produces uniform water flow through the media. It minimizes channeling, significantly improving the efficiency of the filter media.

Suitable for a Variety of Filter Media

Ready to use with carbon and GFO out of the box. Add the optional NPX Screens for bio-pellets, and for CDX carbon Dioxide Media, add the optional CDX adapter.

Multiple Set-up Options

Hang the reactor on the back of the aquarium, install it in line either above or below the tank, or place it up in the sump. The adjustable elbow fittings provide additional installation flexibility, and a 1/2-inch barb ball valve enables flow control.
