Aeration is all about gasses. Aeration mixes the pond so that toxic gasses are efficiently released and life-giving oxygen readily replaces it. An aerated pond will be clearer, cleaner, healthier, and have less bottom muck than a pond without aeration.
An uncirculated or non aerated pond or lake develops a thermocline. This is a stratification of the water by
temperature. The warmer water is at the surface in contact with the air and the cooler water drops to the bottom where
it becomes oxygen starved. Proper circulation and aeration will increase the amount of oxygen at all depths, and
break down the thermocline. Aerating a pond provides a healthier habitat for fish, reduces algae blooms, improves
water clarity and rids the pond of bad smells. Aeration also improves the effectiveness of bacterial products that
reduce nutrients and improve water clarity.
Fish and beneficial bacteria both need oxygen to survive. Additional aeration devices can be the answer to your water quality issues. Proper aeration is vital to having a healthy pond no mater the time of year. In the warm months, it improves the effectiveness of the ecosystem and makes the fish healthier and happier. Use a pond aerator during the winter to not only provide oxygen to the pond and fish but also to create water movement at the surface to help keep an area of the pond from freezing. Use a protective vented cover and keep elevated from ground for winter use.
