The PhosBan Reactor from Two Little Fishies is an advanced chemical filter made for use with fine grained chemical media, including (but not limited to) PhosBan. Water in the reactor is pushed upward through a dispersion plate, "fluidizing" or suspending the media in the reactor column. This allows water to contact more of the surface area of the media for longer, and creates the most efficient chemical filtration possible. It also prevents clumping or clogging of media in your primary filter.
The PhosBan reactor installs above or below your tank, or simply hang it on. Replacement parts (
o-ring; foam discs) available.
