Thanks for the advice folks. We decided to run power to the pond. In the long run we think it will be better for the pond and ensure the system we choose can operate exactly as it’s supposed to. Thankfully where we were working is not rocky and there aren’t any trees so we were able to complete the task pretty quickly. We are going to get the aerator wired for 220/230 and plan on setting up a post mounted unit. Any other suggestions from folks are most appreciated.
