Pond Boss Forums AERATION Should I aerate? What's Your Thermocline here in Mid-May 2006?

I am Michel's brother and I installed the outside air-temp sensor and aerator controller last weekend. The unit is currentlysetup to turn on when the temp dropped to 58 or below and then off when the air temp exceeds 60 degrees. It seems to work well at these temps for the early summer since the recent night time temps have been from the mid forties to mid 50's so we are getting anywhere from 6-10 hrs of aerator action per night.

We hope that churning the water and exposing more of the water to the cool night air will help in keeping the pond cool. Even though we have a 1/3 acre pond, the aerator is oversized with two large diffusers and a 1/3HP 230v rotary vane pump with approx 6 cfm flow. Conversely shuting the unit off when the air temp gets hotter should help. The temp air temp controller is only about as expensive as an intermatic timer. My brother bought it on the net for about $60.
