Pond aeration systems and products are designed to keep your water healthy. To keep ponds clean and healthy, water requires oxygen. Without it, water turns unhealthy resulting in fish kills, algae and bacteria growth and excess muck and organic matter on the pond bottom. You can prevent this by aerating your pond or lake with a windmill aerator, which works with nature to improve pond water with every turn of the windmill or by using an electric pond aerators. Pond aeration adds oxygen to the water, drives the natural pollutants to the surface freeing them from the water, while continuously circulating the water, which reduces stagnancy, stratification and improves the pond environment.
