Sam, one was right under the light, one was on the bottom under the cross brace and the third was up high but right at the side of the tank. Completely different light exposure on them. One acro, one pocillipora and a T. reniformis. No idea why these three out of all the corals. Again, maybe something else changed the same time I did te water change. I'm not chancing it though.....
