I see some of your posts on the Geo Exchange Forum, I find it interesting all the technology involved but all the varying opinion of weighting the loops. I dont see a downside to "anchoring" them down and then if the system ices having the internal system prevention do its job.I think there is some good information on that site.I do not have any winter pond aeration systems operating that has an Airstation near the loops (but not for that reason) I always suggest having a winter Airstation in the shallow section even with cold water fish so your pond can stratify from 39F on the bottom to 33F just under the ice.Rarely in a small pond (1 acre or less) do I agree with the many publications that open water in midwest and northern climates is a good thing.I think the idea of gass exchange being needed in the winter with risking a sub 39F bottom temp is not worth the gamble.One of the things that has changed over the years is diffuser technology and the ability to move massive amounts of water compared to older technology that just made "bubbles" So I believe that aeration in some past situation may now have a problem with todays high volume designs.I only winter aerate if I have snow cover for 4 weeks and then just enough to open an area to re-form clear ice.I run a windmill with the Koender 7-9 inch airstone in my small pond for winter only. I have a bypass valve on one of the legs that will exhaust to the air when I dont want aeration. Consider adding a splitter and an exhaust valve on yours and putting another diffuser in the shallows.Unless you have 3 plus cfm you will not be able to run both in the summer and even at that you will need a lot of constant wind as the compressed air will want to travel to the path of lesser resistance.Outdoor Water Solutions had a display at PB3 that had an electric unit kick in when the wind was not present that may have some merit.Keep in mind that sunlight is the key to oxygen production and not air bubbles from diffusers.I consider ice a needed blanket for warm water fish and open water in small pond a means of letting the heat out.Ill call Carrier today if they dont mail me back as I am curious on their take on the loop weighting and excessive freezing.(sorry about the long post)
