Need help!!

So about 2 months ago i moved my sps into a new 120g setup. Before that those sps were in a frag tank that i turned into a mixed reef of mostly sps some lps and zoas. All corals were doing great. Throughout the transfer process i kept an eye on levels in both tanks adjusting accordingly. Well for the last day or two i have been seeing the frag tank has started to look poor. Chalices are receding and looking bad,most zoas are closed, lps and torches look bad. All sps in that tank look fine. Tested water and levels are good. Any ideas? Going to do a large water change in the morning.

Did you check the pH specifically? I ask because I had lost corals before and water parameters looked great only to find out the pH was awful low.
