Pond Boss Forums AERATION Should I aerate? Windmill Aeration

Windmills do work especially in smaller ponds of 0.75ac and smaller. But the windmills IMO are not as good as an electric system that produces 3-5 cfm of air that can be delivered during low wind or no wind periods and 24/7 if necessary. From my testing windmills do not get pumping a good cfm of air at 8+ft until the wind speed gets up near 10mph. My windmill does not even produce bubbles until it is turing well during a decent breeze. The deeper the pond the more wind speed that is needed to get air released the deeper the diffuser is located. Windmills are definately better in smaller ponds than no aeration. In larger volumes of water there can be issues of not enough circulation and associated dissolved oxygen problems with inadequate turnover per day.
