Marina Slim Filter Zeolite Cartridge 3pk

Marina Slim Filter Bio-Clear Cartridges come in a convenient 3-pack and are compatible with all Marina Slim Filter Models. Perfect for goldfish tanks, these cartridges blend zeolite and Ceramitek into a single unit for optimal aquarium health!

• Removes harmful ammonia to minimize fish stress
• Specifically designed for goldfish environments
• Combines zeolite and Ceramitek for pristine, clear water

The zeolite component efficiently captures toxic ammonia, helping to keep fish stress-free, while the Ceramitek, a porous ceramic bio-filter material, enhances biological filtration for a cleaner tank.

These cartridges are fully disposable and need replacement every two weeks.

To maintain a steady population of beneficial bacteria, avoid replacing all cartridges simultaneously.
