The Marina i110 /i160 Power Cartridges are made specifically to fit inside the Marina i110 internal filter and Marina i160 internal filter.

The outside of the power cartridge features polyester foam to trap fine particles; while the inside chambers contain carbon to remove pollutants and odors; and zeolite to eliminate toxic ammonia for a cleaner, healthier aquarium environment and crystal clear water.

Note: For best results replace every 4 weeks.

Do not replace both cartridges at the same time in order to ensure constant presence of beneficial bacteria.
