I feel your pain. I was adding some frags to my scape and accidentally hit my tower and one side came tumbling done. This was last friday evening.
Friday night @ 11.30 I finally give up and go to bed. Only slept a little, Sat. morning I get up @ 6 am and within a 1/2 hour have it close to what it was.
Sat afternoon after a little tweaking I'm finally happy with it again.
Your corals will color back up, I have found when you mess with them, they will lose some color till their happy again.
