thanks Esshup. I have high hopes you got through the winter ok, and think your decision to turn on the air sooner rather than later was very smart. I watch WBJr's thread all the time about aeration at high altitudes in Colorado, and the discussion about super cooling. I have begun to wonder if maybe more species tolerate a great range of (low) temps than previously thought? There I go guessing again. I trust you and the other professionals and the fisheries biologists, and make every attempt to follow the advice given.
