The PhosBan Reactors are designed with the up-flow 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, the reactor forces an even distribution of water through it, which prevents channeling or clumping. The new design has a convenient screw-top for easy servicing.
