Here's the bad news about geothermal. According to information I just received from Climate Master Engineers via a rep. from my HVAC installers "Absolutely under no circumstances aerate your pond. You want an ice layer to form in winter and the pond to be stratisfied in summer in order for the system to operate properly." This is just in the case of my 1/2acre pond and my system. Others may have different scenarios. If a person is planning to aerate and use a closed pond loop Geothermal system, they should consult their manufacturer or qualified installer prior to installation to see if it is possible or pursue other Geo or traditional alternatives.
