Eheim - Diffusor f. 12/16mm - 4004651

EHEIMDiffusor

The diffusor draws in fresh air from the outside and this enriches the aquarium water with oxygen. 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 also be supplied whenever a cover or lighting system limits the space over the surface of the water, otherwise the oxygen available from this area would soon be used up. Tip: EHEIM VARILUX Aquarium hoods with their caf-Technology (constant air flow) provide air circulation.
