Npx Reactor Screen
A replacement plastic screen for the Two Little Fishies PhosBan Reactor, fitted when the reactor is loaded with NPX Bioplastics or other pelletised media. It takes the place of the foam sponges, holding the pellets above the dispersion plate so media stays put while water flows freely back to the tank. Sold in a pack of two and sized for the 150 and 550 reactors.
