high lighting + low nutrient = pastel color in corals. Some look good that way some look bad that way.

Feed your corals, they are probably anorexic for now. Give them zeovit amino acid, coral vitalizer and Fauna Marin coral food. It is a long shot but they will regain beautiful colors if you feed them right and not let them starve.

Read Coral magazine article ''is your reef anorexic''. it is a good article about low nutrient and starving corals.

My red planet is striking, very red and green at the base. I have about 5 ppm nitrates and .1 phosphates, so it's far from low nutrient. The way I see it, the only advantage of a ULN is not having to deal with algae. The inconvenient is pale pastel corals and problem with LPS and gorgonians.
