"they have fans here in Arizona with the misters mounted on the front of the fan in the air stream, my local discount tire uses one.  They are cool to watch work and do the trick for sure"

"I read somewhere about someone using salt water as the coolant fluid. The added salt increases water's ability to store heat and transport more of it away underground. The saltier the better."

Hello William:

I have been doing aquaponics for about two years but don´t consider myself an expert.  But this is the good thing about it, that you learn something new everyday and have friends to share it with.  Welcome.
