Pond problems

[Terra]

Maybe I missed something, but I don't see an actual water temperature posted.
In Arizona, with the dry atmosphere, it shouldn't be much of a challenge to reduce the pond temperature.
Increase air movement above the pond surface (via aeration or a fan) and provide some shade.

My water temps are definitely not ideal. It has gotten as high as 90 degrees. Usually sits around 84 during the day at the surface and about 70 by morning. My fish are tolerating it well though and show zero signs of stress or lack of oxygen at the moment. Working on building a type of shade structure though.
