I think you are right when it comes to running a volcano where it will lower surface temps instead of running only diffusers and seeing little if any reduction in water temps during the summer. Some experimenting is going on right now and seeing how adding a sprinkler can reduce surface temps 7 degrees. It's too early to say any more at this time, but maybe more info later on.
