Help! Why are these coral unhappy?

[durt.kobain]

Can someone tell me how best to attempt to recover these.. a green colt on the left and a moon coral on the right. I’ve moved them both to the bottom of the tank to reduce light in hopes these will do better. My salinity is 1.025, calcium is 460 and kh is 9 to name a few parameters.

How can I do my best to recover them?

Nitrate spike?

Nitrate spike?

Yes I am working on nitrate levels, using NoPox for this issue. Any other means to lower nitrates? ( I know the classic waterchange as well)
