I guess I am one of the pond ecological experts here since I've taken numerous college courses in biology and then achieved an advanced degree in aquatic biology. The impact of under aeration has a lot to do with biochemical oxygen demand of the pond water. The more enriched and eutrophic a pond is, the more under aeration becomes a problem. As mentioned it has to do with how fast the water on the bottom is loosing its oxygen. Numerous variables control this. About the only way to determine rate of DO loss is measure it which I have done a few times in local ponds.
