This should be a great exercise in learning. Cary makes an important point that has application to many pond management functions in addition to aeration ( feeding , fertilization , liming , pond turbidity fixes , stocking methods , pond assessment methods, weed management and more ) EACH IS A TOOL IN THE POND MANAGEMENT TOOLBOX TO BE USED PROPERLY. The point --- A chain saw is not the tool to use to fix a faulty power outlet. \:\)

A couple of thoughts to ponder.

1. Effect of bottom diffused air aeration on plankton blooms and the food chain during warm water and cold water periods.

2. The many types of aeration (not just circulators and diffusers) and their purpose (pond bottom clean up or avoiding the dreaded 15 min. of low O2}.

3. How the physics of pond size and shape (including bottom configuration) effect your efforts.

4. How carrying capacity and or feeding effects the need for aeration.

5. The right time, place, method and manner of aeration.

Here is one method used in commercial pond management systems.
