The genuine Marina Bio-Clear replacement cartridge is designed for all three Marina Slim filter models (S10, S15, S20).
Ideal for goldfish, it contains zeolite and Ceramitek filter media for optimal filtration and a healthy aquarium.
The zeolite effectively absorbs toxic ammonia and reduces the stress suffered by the fish, while the Ceramitek filter medium, based on highly porous ceramic, maximizes the action of biological filtration.
This disposable, easy-to-use cartridge should be replaced every 2 weeks to ensure optimal results. To ensure the continued presence of beneficial bacteria, never replace all cartridges at the same time.
