Eheim air diffuser

The diffuser sucks in fresh air from the outside, injects it inside and this enriches the aquarium water with oxygen. The supply of this element is necessary, especially for poorly forested aquariums and for those with cold and sea water. Air must be supplied when the coating or lighting system restricts the space above the water surface. Otherwise, the available oxygen from this area will soon be used up. Tip: EHEIM VARILUX aquarium hoods with their special technology (constant air flow) ensure air circulation.
