If the well water is 65 degrees, and you have to keep things under 70 degrees F, that's not a lot of margin considering what the ambient temperature will be in the structure where you house these tanks.

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.
