PhosBan Reactor 150 – Two Little Fishies
The PhosBan Reactor 150 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.
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.

The reactor works well with my filter media. Water distribution is even and no channeling occurs. I mounted it below the tank and it fits perfectly. The ball valve makes flow control easy and the setup is simple to assemble.

I’ve used it for a few weeks now and it’s helping with phosphates in my tank. The upflow design is effective and the included valve allows me to adjust flow as needed. Installation was straightforward.

Great product for maintaining chemical filtration. The even water flow prevents media waste and keeps the filter efficient. I appreciate the flexibility in mounting options.
