i have a few sps and how do i know that they are getting enough light. i have frags of these coral i dont know the name but have pics of the colony. they are all about 7-8 inches from water surface and the lights are about 5-6 inches off the surface. they seem to be doing good but they dont look as good as where i got them from.
