Cecil,
Do you have problems with freezing in the winter? We are also looking at geothermal with an open loop, discharging to the pond. At 20 gpm, that is lots of water pouring onto the surface of your ice. I use our pond for skating and ice fishing. I am worried that that much discharge would cause slushing and uneven ice. Our pond has about 1/2 acre of surface.
Maybe this is why you put it under the surface, but I heard that pumping water into the pond without aerating it can cause problems as well.
