Marina Slim Filter Zeolite Cartridge 3 Pack

The Marina Slim Filter BioClear replacement cartridge fits all 3 Slim Filter Models.  BioClear is ideal for golfish, and it combines zeolite and Ceramitek in 1 cartridge for a healthy aquarium.  The zeolite effectively absorbs toxic ammonia and reduces stress on fish, while the Cermitek, a highly porous ceramic biological filter medium optimizes biological filtration.  This easy to use disposable cartridge should be replaced every two weeks. Never replace all filter cartridges at the same time in order to ensure that there is a constant presence of beneficial bacteria.
