Agreed, but right now it has hardly any zooxanthellae to protect it from the lights, so moving it up right now would roast it. Don't you think?

50/50 really. I've moved bleached pieces up high without issue, and with issues. I would at least start moving it closer. Maybe go halfway back up and leave it alone for 3 months, see what it does.

I have a piece of bonsai coral that did the same thing. It was up closer to the top, about 12 inches from the lights. Moved it down to about 18 inches down and the colour has returned on the new growth. My Valida was high up as well colour was drab on it as well. Moved it down and it seems to be colouring up too. I also had some hammer coral on the bottom of my aquarium turn white and moved them into a large cave under my live rock (out of the direct light). They coloured up after a month.

I do have several sps coral high in my aquarium, red planet, cali tort, purple pocci, green elkhorn, blue tip - green slimmer, orange & forest fire digi, purple cross and lots of different montis. They all seem to very well. I also have some others that have good colour, but the growth isn't great. These include, pink lemonade, pearl berry, Hawkins coral.

If my lights are too intense, should I move them up? They are currently 6 inches above the water. What height should I move them to?

And thanks everyone. Really appreciate the help!

too many variables. how do you arrange your rock ? Does your light have the option to on/off some bulbs or dimmable? Easiest way is to move the light up - starting with 6" ? And find the sweet spot. I am no expert though.

Yes, standard 90 gallon. 2 lights are on 12 hours, 4 others are on for 10 hours. Not dimmable. Rocks are arranged in a lattice wall (see picture)

In general, I think 12 hours is a bit much for lighting cycle. I prefer 7 or 8 for main lights.
