Ok I getting concerned about my pond right now. Been running the shallow water aerator (3' deep) all winter when the temp is below 35, which most of the winter has been. For most of the winter the hole keep open was about 40' by 40' all the way to the shoreline. Since last weeks snow storm and the cold since the hole has gotten smaller and smaller and now it is only 2' in diameter. Is it by chance I have cooled the water in the pond to the point where my fish are in danger? Hoping the coming warming trend helps things out.
