I have (2) 1000 gallon stock tanks I want to raise fish in.
I'd like to keep the water cooler during summer. I wondering about
installing a SMALL geothermal loop underground say 6-7 feet deep
To cool water when it's hot. I was thinking of say a 20' long trench
With what ever I can fit in it for pipe. Most likely coils, say a good 100'.
I do have a few lengths of stainless 1-1/2 pipe I could bury if that would
transfer heat better. I was thinking of a separate slower pump than
the filter just for cooling. Ideas??
