Agree bro.

What I did, besides airpump, is the cheap alternative of blowing air across the water surface using a powerful fan. Managed to reduce temperature by 2 to 3 degress over night- so by morning the temperature is around 27+ degrees.

I expect lower temperature when the cooler season arrives at the end of the year.

Only issue with fan is the need to constantly look out for bad weather if pond is outdoors.
