I had to take some serious emergency steps because I didn't have aeration installed yet. Backed my gatortail mud motor into the pond and fired it up to circulate the water. It did a fantastic job of creating a good current around the pond and lowering the surface temp back into the high 80s in no time.

I haven't had those kind of surface temps since I installed my system, but I only see a variance of about 3 degrees from top to bottom now with no thermocline. I only have to run the pump about 6 hours to get a complete turnover so I set it up to run from 2-8am when it gets really hot outside.

.10 surface acre pond, 10.5 foot deep. SW LA. The epitome of a mutt pond. BG, LMB, GSF, RES, BH, Warmouth, Longear Sunfish, Gambusia,Mud Minnows, Crappie, and now shiners!!...I subscribe!!
