The Red Cap might be to high in your tank. Try to lower it down some.Bought a few frags to see how they would do. The milli is growing good and holding its color well. The red cap turned pink and seems to be bleaching out. What would cause this
Yeah move the SPS down. Probably just too much light. Sounds like you got a good amount going. Start em low and bring them up slowly till they are where you want them.
