Marina i25 Internal Filter

Whether youre a beginner fish hobbyist or have kept an aquarium for many years now, youll find Marina products to be user-friendly and affordable, supporting the life and habitat of your fish for years to come.

The Marina i25 Internal Filter is a powerful filter designed to easily fit into the aquarium using the included secure suction cups. Complete with a specially designed power cartidge this is an exceptionally quiet unit. The filter provides 3 - stage filtration - mechanical, chemical and biological. Toxic ammonia is removed in the zeolite chamber as water flows through, before entering a second carbon filled chamber that eliminates pollutants and bad odours and finally the third layer, which traps debris inside the cartidge. The filtered water is then returned to the aquarium via a waterfall spout, which provides continuous oxygenation.

Feeding Guidelines

These are broad guidelines only, designed to assist with feeding your pet based on their weight, age and activity level.

Required amounts may differ between individual pets, and adjustments may be required to maintain optimal body weight.

Once or twice daily feeding is recommended for adult dogs, unless otherwise specified by your veterinarian. Puppies and kittens require feeding more regularly, with the total portion divided into three or four meals throughout the day. Ensure fresh water is available at all times.
