Marina i25 Replacement Power Cartridges are made to fit in the Marina i25 internal filter. The unique design of these cartridges allows water to easily filter through the center of the cartridge.
Each cartridge is split into two separate chambers: the first chamber is the zeolite chamber to remove toxic ammonia and the second chamber is the activated carbon chamber so that pollutants and odors get removed.
The water finally enters the floss layer last where the debris gets trapped inside the cartridge. This helps keep your aquarium water crystal clear!
For best results, replace cartridge every 4 weeks.
