Mike, Just checked temps after the 3/4" of rain we got yesterday and after 4 days of running only at night. Temps are now 82 top to bottom. Since there is still no variance, I am going to take your advice again and start slowly cutting back an hour at a time now. Im just relieved that things have cooled off some but I also realize that more heat is on the way. Nighttime only definitely seems to be helping though. I would like to add some type of surface aeration to the mix but I have no power close to the pond. I had to pump air over 300' to get what I have now so, hopefully, I'll be able to get by with just bottom diffusers.
