I think it is beneficial if one drills or makes a hole in the ice over the diffuser before starting winter aeration. This reduces excess air under the ice that will occur until the moving water erodes a hole in the overlying thick 4"-10" ice sheet. Once open water above the diffuser is crated then it only takes minutes to daily remelt the ice above the diffuser.

Strong or constant winter aeration in heavy ice cover small pond may overly stress a pond full of or overloaded with warm water adapted CC.
