When fresh air feeds into aeration nanotubes in water, the nanotubes will expand and a fog of tiny bubbles (0.1~2mm) generates and drifts slowly in water, thus it can help oxygen effectively dissolve into water (energy effect: 6kgO2/kW.h, O2 availability: ≥20%), one set of 1kW roots blower can equip 200m nanotubes to aerate a fish pond of 2000~4000m2 (2m depth). The nanotube can be applied in water as deep as 10 meters, and can twine around wire into spiral other form.
