I don't want to risk it, the pond is only a 1/4 acre. Winter aeration might get a few RES but more importantly I have dogs and don't want to mess with having areas of thin ice. Years ago at my dad's old pond their 15 year old dog went out on the ice where the heat pump discharged into the pond, she drowned next to the dock in shallow water on a very cold Christmas morning. I will fire the aerator back up when water temps are back into the mid 50's.
