Outdoor Water Solutions pond aeration systems and products are designed to keep your water healthy while you enjoy your water. 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 with a windmill aerator, which works with nature to improve pond water with every turn of the windmill or by using one of our energy efficient AerMaster 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. Outdoor Water Solutions accessories keep your pond healthy with pond dyes, all natural aerobic bacteria, muck pellets and windmill water pumps.
