I too don't think you will have a problem. My pond is about 0.6-0.7 acres, and about 8-9 ft. deep. I'm usually iced over from about early-to-mid December until mid-to-late February. I've never had a problem that I know of. Snow either blows off my pond, or it melts and refreezes, so I've never bothered to remove it. I do not have an aerator.
