Ted,
I hope you're right.
You know what's interesting? A couple of years ago (or maybe it was three years ago) when I set up the Kasco near the pier with sub zero air temps, it didn't effect my perch or bluegills at all. Of course the open water fish could get away from it but I had some fish in cages very close to the aerator and no fish lost.
I also was amazed how little the temperature dropped in the 30 foot open area created by the diffuser even with subzero temps. There was steam rising but temps still stayed in the mid thirties on the surface.
Perhaps if I had run it longer than several days I would have seen a drop. Thankfully I didn't have to, as not long after that we had a major thaw.
