The Marina i25 Internal power filter is a compact and neat internal filter but very powerful and capable of filtering aquariums up to 25 litres.

This filter is safe for both tropical or goldfish tanks and clips securely onto the side of the aquarium with the powerful suction cups. A fully submersed internal filter so extremely quiet! Also comes complete with a power cartridge which when needs replacing is effortless and mess free (only recommended to change every 4 to 6 weeks).

The filter is designed to let water enter the centre of the cartridge for an effectrive mechanical, chemical and biological filtration process. Upon entering the second chamber the water goes through a zeolite chamber which absorbs toxic ammonia. The 2nd chamber contains carbon so polishes the water and removes pollutants and odours. Any floating debris is trapped inside the cartidge. All to ensure the water is crystral clear!
