Pondpro,
To further my understanding, can you explain your comment below against the experience of others in the posts below yours? Perhaps this is a situation that requires some explanation of the 'it depends' part of the equation?
I'm curious because up to this point in time, I thought I could cool my pond by running my aerators at night and get the cool water from the air temps to 'flip' back under to the bottom. But now it sounds like real life experience from other pond owners suggest you will only warm and destratify the whole pond to 70 degrees by running the aerators at night.
Makes me wonder how to keep the bottom cool? I do have the option of pumping 53 degree well water to a pipe that comes out on the pond bottom, but I imagine again with my diffuser running that mixes through pretty quickly. I can only run the pump a few hours during the overnight as the pump is needed at full capacity to run my sprinklers and my house water needs during the day. I can't imagine I can pump enough water in my 1/3 acre pond to totally exchange the water or even to bring the level up.

Do NOT worry about warming the water temps by installing an aeration system. If your pond will be 15ft deep, the temps below the 6ft depth will still be in the sub 60 degree F which will sustain your trout population.
