Mike, I've been waiting for someone a lot more knowledgeable to speak up, but they haven't yet.

I have no idea if what you did had this effect, but so long as you don't have a fish kill or fish sucking for air desperately at the surface, likely the harm (if any) is temporary. 99 degree water risks permanent damage, in my view.

But I admit to just being a pond owner, not a fisheries biologist, so maybe I've got it wrong! If so I hope they will correct me so both of us can learn.
