Julian Sprung's Reef Aid - Phosban Reactor 150
The PhosBan Reactor 150 is 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.
Spare foam replacement discs also available.
