Hi all, I'm looking at building a pond in South Louisiana. I plan on stocking the pond with bluegill and bass. I also want to use the pond for geothermal and plan to dig to 20ft (assuming the soil is ok). I've read about hypolimnetic aeration a bit and was curious if anyone had success on this? Or would it be possible to mount an aerator about 10 ft up on a platform? This would allow for aeration with the surface but wouldn't affect the deep layers much (I think). I'm trying to avoid a fish kill scenario but also have water cold enough for geothermal.
