Replacement filters for Marina 5G/10G starter kit Filters.

Marina Slim Filter Bio-Clear is a genuine replacement cartridge for all three Marina Slim Filter Models (S10, S15, S20). Ideal for goldfish, the filter cartridge contains zeolite and Ceramitek for optimum filtration and a healthy aquarium.

The zeolite effectively adsorbs toxic ammonia and reduces stress on fish, 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.,
