Most of my photos are under mostly actinic, which gives the blue tint you see. It is best to keep them in low lighting like this. Maybe you have a shaded spot in the tank? Remember where ever you put them, if you decide to bring them home, they will need medium flow as well. And if you have had any algae problems recently I would just forget it. I have never had an algae problem ever and I still get lots of algae growth on my gorgs which causes the polyps to recede and it just makes an unhappy coral.
