This isn't the case with my tank. My corals were all used to the 2x39w T5s in a 16" deep tank with T5s about 4" off the water surface, and it was the halides that I slammed onto there. Funny thing is that the halide fixture also included T5s, but now the bulbs were all 8" off the surface. The LPS improved colors quite quickly when the lights were changed. The exact same T5s were used in the new fixture. So the difference was height and halides.
