Ran the system for a total of 10 hours yesterday, 4 hours of the afternoon and 6 hours last night. Haven't seen any change in surface temps so far. I checked it at 3:30 this afternoon and it was still mid 90's. What I did notice was the fish weren't nearly as enthusiastic on the feed today. They did eat everything, but they were more content to feed subsurfacely, instead of thrashing on top. I dont see any signs of stress. The water is a nice, olive green and visibility is approximately 24-30 inches.

Has anyone else experienced this?

I plan to continue expanding the run times until I reach 12 hours, running only at night now since I'm on a timer. Tonight's run is planned for 8 hours.
