Product Information

The Marina internal filters are a a compact yet powerful range of internal filters, for use with Marina goldfish aquariums, or any other goldfish or tropical systems. They effectively filters water through 3 stages of filtration, providing a cleaner and healthier aquarium environment.

They filter through a uniquely designed Power Cartridge (one included), which enables the water to enter the center of the cartridge for an effective mechanical, chemical and biological filtration process and then exit from the polyester foam layer, which leaves all the trapped debris inside the cartridge, ensuring your aquarium water is crystal clear
