Dead organic biomass forms dark sludge at the bottom of the water body - this creates an increasingly hostile environment. The gentle aeration attracts aerobic microbacteria through oxygen - these metabolise the organic matter and bind pollutants to the sediment.

Organic matter makes up the largest volume of sediment - biological degradation prevents the formation of gases that are harmful to the climate. It also prevents sedimentation, as no swamp-like zones can form.

Breeding birds and protected plants are preserved with this measure - the gentle oxygen therapy is an ideal measure to bring nature into harmony with artificial surroundings. With a bit of luck, crucian carp, moderlieschen and kingfisher will settle with you.
