Two Little Fishies NPX Screens for Phosban Reactors – 2 pk

Two Little Fishies NPX Reactor Screens allow you to convert your Phosban Reactor 150 or 550 for use with the NPX Bioplastics Media. These specially designed screens take the place of foam disks, and prevent the pelletized media from passing through the dispersion plate of your reactor. Simple instructions illustrate how to cut the screens for a perfect fit. NPX Reactor Screens can also be used with other compatible cylindrical reactors.
