The PhosBan Reactor by Two Little Fishies is designed with the upflow principle to achieve the most efficient use of PhosBan or other chemical fitler media. 

By pushing water from the bottom upward through a dispersion plate, it forces an even distruvution of water through the media.

The PhosBan Reactor can be seated upright in the cabinet, in the filter sump, upright on the floor below the aquarium or hanging on the side or rear of the aquarium. Where ever it is located, the reactor must be upright and level to operate properly.

Hose barb connections are for 1/2 inch i.d. tubing. Includes 1/2 inch barbed ball valve for flow control, and hose clamps. Use with any pump having a capacity between 100 and 250 gph, but regulate the flow rate to the recommended 20 to 30 gallons per hour with the included ball valve.

NOTE: Do not use a media bag in the PhosBan Reactor.

Multiple reactors may be used for large aquariums.
