Bio-Carb cartridges for Marina Slim filters, 3-pack
$9.79
The authentic Marina Bio-Carb replacement cartridge is designed for all three Marina Slim filter models (S10, S15, S20). Ideal for tropical fish, it contains activated carbon and Ceramitek filter media for optimal filtration and a healthy aquarium.
Activated carbon effectively removes pollutants and odors, while the highly porous ceramic-based Ceramitek filter media maximizes biological filtration.
This disposable and easy-to-use cartridge should be replaced every 2 weeks for optimal results. To ensure the continuous presence of beneficial bacteria, never replace all cartridges at the same time.
