How do you keep a pond from turning over?

The only way to prevent turnover is to eliminate stratification and keep the pond thoroughly mixed all year long. This can be accomplished by installing a bottom diffused aeration system. The bottom aeration will prevent anaerobic conditions from ever getting established at the pond bottom.
