Question: After reading on this forum about "super cooling" a pond from too much aeration and that fish don't do well in near 32 degree water, I was wondering why my minnows in a sinking minnow bucket in 2 feet of water less than ten feet from Dwight's circulator are all alive and ready to go fishing? The water can't be much over 32 degrees in this spot. Heavy ice all around except for the open water area created by the circulator.
