Unfortunately, if this heat continues in the Midwest, this won't be the last post of a kill off. I'm right in the middle of one, 1 acre pond with 3 diffusors...didn't help. It was sprayed several days ago. My Kasco surface aerator is burned out, that might have saved them. Nothing I can do now. I would advise anyone in the heat zone not to spray right now, aeration or not; half treatment or not.
