diffusers

diffusers by EHEIM - The supply of oxygen is recommended especially for weakly planted aquariums or those with a strong fish population.

Also for cold and seawater basins or for fishes they need more oxygen.

Even where a cover limits the air space above the water surface, air should also be supplied. The oxygen from this area would soon be consumed. 

Note: VARILUX aquarium covers by EHEIM provide constant air flow (caf) for air circulation.

- To be recommended. In aquariums with little plant growth or strong fish population
