The Marina i25 Filter Replacement Cartridge is crafted for seamless compatibility with your Marina i25 internal filter, providing unparalleled water clarity. Its innovative design channels water through a central pathway, ensuring thorough filtration at every stage.

As water journeys through this dual-chamber cartridge, the first stop is the zeolite chamber, which effectively eliminates toxic ammonia. Next, it flows into the activated carbon chamber, cleansing your aquarium of pollutants and odours. Finally, the water passes through the floss layer, capturing dirt and debris, resulting in crystal-clear water. For peak performance and pristine water quality, it is recommended to replace the cartridge every four weeks. This package includes two Power Cartridges.

• Effective Filtration: The multi-stage process eradicates ammonia, pollutants, and debris for a healthier aquatic environment.
• Regular Replacement: Ensure optimal filtration by switching out cartridges every four weeks.
• Unique Design: The water-centric entry system maximises filtration efficiency.
