Concerning Southern ponds, just how hot is too hot? I recently installed an aeration system and after a month or so of running 24/7, the water is finally looking better and starting to get a little clarity back (Secchi depth was about 12" soon after starting but now is up to about 18") However, with the aeration I now have zero thermocline and yesterday temps were 87 degrees top to bottom. (Avg depth 6-7') I realize that is getting close to the upper limit, however, you would never know it by the fishes behavior. Everyone seems to be thriving and feeding is just as strong as it's ever been. Which begs the question, just how hot is too hot? Do I really need to switch to a nighttime only schedule even though everything seems to be fine? I'm just wondering if Southern based fish are maybe better adapted to the heat and therefore can tolerate higher temps than they would elsewhere? What do you guys think?
