Marina i25 Replacement Power Filter Cartridges – Multipacks

Keep your aquarium water clean, clear and healthy with Marina i25 Replacement Power Filter Cartridges. Designed specifically for the Marina i25 Internal Aquarium Filter, these replacement cartridges provide effective mechanical, chemical and biological filtration to help maintain a healthy environment for your fish.

The unique Marina Power Cartridge design allows aquarium water to enter through the centre of the cartridge and pass through the filtration media before exiting through the polyester foam layer. This helps capture suspended debris, remove unwanted impurities and support beneficial bacterial activity.

Ideal for routine aquarium maintenance, these convenient replacement cartridges make it easy to maintain the performance of your Marina i25 filter without replacing the complete filtration unit.
