Aqua One Ceramic Cartridge – Moray 320/320L 417c

A replacement Ceramic Cartridge to fit the Aqua One Moray 320 and Aqua One Moray 320L internal filter. 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 perhaps every six to eight months.
