Glad to see the corals are adjusting to the lights, more so that you are adjusting to the new lights.
I have been thinking about adding some Fiji pink T5's for some time since Chris retrofitted his tank with them but truthfully I really don't think we need it. The color of the coral doesn't seen to change much instead the reflection under different lighting system alters it's true color. I had a piece from Peter's tank that looked brownish with white polyps under his AI sols but once I put it in my frag tank with T5s 3 whites, 2 blues, and 1pink. That piece instantly changed into a redish purple body with white polyps. Same with a bubble gum nana I got from JL a week and half ago. The body under T5 was baby blue and as soon as it hits my tank the blue washed out and the body just look like its bleached white, I took it back to the JL just to see that I am not mistaking and as soon as it hits their water BAM the piece turned baby blue. I am not gonna pretend that I am some kind of light spectrum expert but I do know that coral grows and they do keep color under LED but to make them "pop" we should supplement it with a red spectrum so it will be more asethetically appealing.
