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.
We at the Menagerie recommend periodically replacing 1 cartridge at a time on a semi-regular basis, as the Carbon will stop working after approximately 1 month of use. Between replacing cartridges, all cartridges should be gently cleaned off in dechlorinated water/aquarium water as part of regular aquarium maintenance.
