I think your corals are starving. You should try zeovit amino acids and coral vitalizer, a little drop each day. That really revived the color of my coral.

Your calcium is too low.

I used Chemiclean a few times without any effect on my corals, SPS or LPS or soft or even the gorgone. The only thing that hapened was that one of my photosynthetic sponge in my nano went white and I thought it would die but it has recovered since, fortunately. I will never use Chemiclean in that aquarium again because that sponge is precious to me (unavailable for sale) and I don't want to lose it but none of my SPS were affected. Photosynthetic sponges are often in symbiose with type of cyanobacteria and thus some sponge may be affected by Chemiclean by losing their symbiotic partner.

I suspect the corals need acclimatation to the new light and they are just plain starving.
