Two Little Fishies PhosBan Reactor 550

The Two Little Fishies PhosBan Reactor 550 is designed with the upflow principle to achieve the most efficient use of PhosBan or other chemical filter media. By pushing water from the bottom upward through a dispersion plate, it forces an even distribution of water through the media, and prevents channeling. It can be mounted hanging on the back of the aquarium or below the aquarium.

  • Use with a maximum of 750 grams of Phosban.
  • Reactor is rated for up to 600 gallons.
  • Recommended flow rate: 20-40 gph.
  • Uses 1/2" I.D. vinyl tubing.
