Take a temperature reading of the pond water during the day. Use a swimming pool thermometer and measure the top 12" of water and let us know what the temperature is.


Now for the other guys that say aerate only at night because the water temperature won't get as hot. Give me some concrete numbers please. What is the surface water temp during the day vs. at night in a pond that isn't aerated? How much does the temp change from day to night?
