You bring up a very good point here and i don't think a lot of people realizes that could happen. I bet it has happened before and was shrugged off because they believed it was another problem. You asked the question "Anybody esle had this problem" and i wanted to simply put "no i haven't but good catch!" and i realize i have had corals upwind before and they started RTN so i moved them and they were ok. I think this happens alot but know one thinks about it.
Great post.
