You'll also have to do some kind aeration, so the consideration of what temperature the 'air' is will play a factor too, I think.

I believe all well water is essentially devoid of dissolved O2, so getting that water 'usable' may have a temperature change consideration.


Sunil, when Cecil was using the packed column type of aerator, he saw a reduction in well water temps during the summer due to evaporation cooling the water running through the packed column. Cecil can keep the water in his 1/10 acre pond in the low 60's with 54°F well water. If the water is too warm in the 300gal tank, the OP could always plumb in a chiller to cool the water more.
