Eheim Diffusor 19mm

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.

The small diffuser is mounted at the end of the inlet hose close to the surface of the water and is fixed on the tank wall to create an injection angle which is as flat as possible. Simultaneously this effectuates an excellent movement of water. The air hose of the diffuser is led to a place outside the aquarium. The quantity of sucked air can be dosed with the aid of the enclosed pressure adjusting clamp as necessary. The diffuser mixes the supplied air flow with incoming water which is injected under the surface of the water by the pressure of the filter pump.
