So our new house has a pond with the GeoThermal lines in the pond. My question is the previous home owners had the aerator running 24/7 365 days a year... I'm questioning is that even good for the pond and it seems like it would be hurting my energy efficiency. ( One that we have a pump running non stop and two that the aerator is not keeping the cool water on the bottom.

I am in the process of installing a Solar system that will be tied in with the Grid and really watching where we can cut electric.

Any advice?
