Mark, the AoG post actually shows polyps grown at two different depths; the left hand picture is on the sandbed, and the right hand picture is a polyp that sits about 6" below the surface. I also posted up the picture of what happens to Kryptonite under very high lighting.
Like you I also have the Pink and Golds, unfortunatly mine all have the lost the nice "pink" and have more the fairy dust appearance. I was told this was due to tank chemistry rather than lighting. Any thoughts/experience on that one?
