Marina Slim Filter Carbon Plus Ceramic Cartridge -3 Pack- 3 Cartridges each

Marina Slim Filter Bio-Carb is a genuine replacement cartridge for all three Marina Slim Filter Models (S10, S15, S20). Ideal for tropical fish, the filter cartridge contains activated carbon and Ceramitek for optimum filtration and a healthy aquarium. The activated carbon effectively removes pollutants and odours, while the Ceramitek, a highly porous ceramic biological filter medium, optimizes biological filtration. The easy-to-use disposable cartridge should be replaced every two weeks for best results. Never replace all filter cartridges at the same time to ensure a constant presence of beneficial bacteria.
