So far so good. No new floaters since wednesday evening. Bumped up the run time to 10 hours last night. Actually ran it from 9PM-7AM to take advantage of the cooler temps. I have now run it 9 evenings and just hit 10hrs on the 9th evening. All the fish seem to be maintaining activity and water looks healthy and clean.

Any thoughts on going ahead and pushing it to 12hrs tonight? This will be the 10th night.
