EHEIM - Diffuser 4003651 - Diameter 12/16 mm

The Eheim Diffuser draws in fresh air from outside and enriches the aquarium water with oxygen as it exits an external filter or pump. This model is suitable for 12/16 mm pipe.

The oxygen supply is necessary especially for aquariums with sparse plants, for cold water and saltwater tanks or for keeping oxygen-loving fish. Air should also be supplied whenever a cover or lighting system limits the space at the surface of the water, otherwise the available oxygen in this area will soon be exhausted. Tip: EHEIM VARILUX aquarium hoods with their café technology (constant airflow) ensure air circulation.
