The Two Little Fishies Little Reactor 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.

Because of its small size, the Little Reactor is ideal for use with Nano Reef and Pico Reef aquariums or as a small stand alone media reactor, and it fits perfectly in standard frag display tanks used at frag swaps.

Pump and tubing NOT INCLUDED
