Replacement: Marina Slim Filter Bio-Clear is a genuine replacement cartridge for all three Marina Slim Filter Models (S10, S15, S20).
Ideal Usage: Ideal for goldfish, the filter cartridge contains zeolite and Ceramitek for optimum filtration and a healthy aquarium.
Helpful Filtration: The zeolite effectively adsorbs toxic ammonia from your aquarium water and reduces stress in your fish. Ceramitek, a highly porous ceramic biological filter medium, optimizes biological filtration.
Easy Installation: The easy-to-use disposable cartridge should be replaced every two weeks for the best results. Never replace all filter cartridges at the same time to ensure a constant presence of beneficial bacteria.
Multi-Pack: Includes 3 replacement filter cartridges.
