Eheim Power Diffusor 7478900

Power Diffusor

The supply of oxygen is necessary particularly for sparsely planted aquariums, for cold and sea water tanks or for keeping oxygen-loving fish. Air should be supplied additionally whenever a cover or lighting system limits the headroom over the surface of the water. Otherwise the oxygen available from this area would soon be used up. 

The EHEIM diffuser supplies fresh air from the outside whose oxygen content aerates the water uniformly.
