The Two Little Fishies 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.
