Pond aeration is a crucial component in the health and functionality of your feature. It is beneficial in every season and during all parts of the day. During the evening it helps oxygenate the pond when plants are not. During the winter it helps break down layers of stratification, helps keep an opening in surface ice for out-gassing, and functions as the oxygen source. In warmer months dissolve oxygen levels are generally lower, aeration helps all biological processes and creates a more stable environment, resulting in healthier fish and plants. With the Savio2 Aeration System, you can sit back, relax, and enjoy your beautiful water feature!
