Pond Boss Forums AERATION Should I aerate? Aeration in the winter

The chief concern with over-aerating in the Winter is supercooling water temperatures. When it's cold enough for ice to form, the warmest (because it's the most dense) water in the pond is 39 deg F down on the bottom. Blow that up to the top to melt ice and fish are losing their warmest refuge. Do that 24/7 and you could really cool off the deep water.

Ice cover is a problem primarily if it isn't clear enough to allow light through for photosynthesis to replace dissolved oxygen. I only run shallow water aerators long enough to melt a hole through dirty (snow covered) ice if it has been around for about a week. Given that Mizzoo is farther South, I personally see no need for you to do differently.
