I want to cool the 1500 gallons of water in my AGP from 98 degrees F down to 90 degrees (or less would be even better).
I built an aeration system to do just that, but it didn't cool the water down more than about 4 degrees, due to lack of temperature differential between the air and the water (it was, however, very effective at reducing the TA & increasing the pH).
I am considering pumping the water through a radiator which will have cold air from a window unit air conditioner blown through the fins. I work at a trucking company, so getting a large radiator is not an issue.
Ambient air temperature here is around 100 degrees F, give or take 3 degrees. I know that window unit air conditioners can blow air in the 65-68 degree range in this climate, so I'm anticipating a 30 degree temperature differential between the air and the water.
My question is: could there be any chemical interaction between the chlorine in the pool water and the aluminum in the radiator?
Also, is there anything else I need to take into consideration?
