Bill, I have been running it 24/7. Two years ago I had a major spring inversion, with every fish at the top of the pond sipping air. There are about 20 acres draining to my little pond and you can imagine what a cold spring rain does. Goes straight to the bottom, and brings the bottom water to the top. So since that event, I have ran it as a safety measure. I imagine that once summer comes I can run it at night only. Also one of my goals was for this to not only be a sport fishing pond but also a food fish pond, hence the CC. I had planned on taking 10 out per year, and replacing them as I removed them. Maybe water clarity and channel catfish production are mutually exclusive
