I agree. With only 2-3 weeks of ice cover you should not have to worry about aeration UNLESS the pond is shallow(5-8ft) and turbid with less than 2 ft of water clarity. Deeper ponds of 11-16ft can go 5 to 8 weeks of ice and snow cover without any DO problems. Ponds deeper than 16ft usually do not need to be aerated during winter if snow and ice cover melts by mid to late March.
