I truly do appreciate all y'all help. Hubby and I are at a loss that this has happened. I want the proper fix, "don't blame the aerator." Ted Lea I would be very interested in what Carrier tells you. We put aeration in because we didn't want the pond bottom to get stagnant and everything I read led us to believe that aeration was a good thing for the pond and fish and in the winter kept the pond from freezing over. Sure, I can move the hose to get the stone in the low end, but I question whether that is really what caused the loops to float. Ours is a one acre pond, windmill is 20' up, I'll check on the cfm and get back.
Jeff,I'm not offended. The HVAC company people are reputable and I believe are just as much at a loss as me. I'm starting to believe these loops have been the root of my problems with our geo system all along--one way or the other.
