Aqua One 127c Ceramic Cartridge Reflex 35

A replacement 127c Ceramic Cartridge Reflex 35. The cartridge is packed with Porous Ceramic granules and forms the very important Biological part of the filtration process. The Ceramic Cartridge can be rinsed out in a little aquarium water for a few months but the ceramic granules eventually become clogged and the cartridge should be replaced  every six months.
