Pond Boss Forums AERATION Should I aerate? aeration in winter

I agree. That's why I prefaced my statement with "if you have to aerate in the summer" then do it at night. For your trout scenario then I would not aerate at all. You are warming the cool bottom water by mixing it with the 80 degree surface water. The cooling by aerating at night would not be enough to compensate for that. Let's ask the question another way, do you think a pond aerated in the middle of hot days will rise in temperature faster over time than one aerated during cool nights or no difference or hot day aeration will result in cooler water?

For winter I was thinking more a 0 degree day with howling winds vs a nice sunny 35 degree day but even in your scenario I would think there will have to be a difference, the greater the temperature difference between the water and the air (wind is also a factor), the more heat that will be lost. Is there a huge benefit, I doubt it but as stated above, I figure every little bit helps.
