Thanks for the input Tracy!

I think you're probably right. In 6 hours I add 12000+ gallons of well water which is a tiny percentage of the pond capacity. It probably has insignificant impact on either temp or DO. The one thing it does do for sure is raises the water level just enough (benefit of a small pond) to get water out on top of the ice more and clear a larger area of snow than that provided by aeration alone. I don't aerate that often during the winter but I'll go ahead and use the well when I do to see if there are any bad effects.
