Sometimes RTN can trigger a cascade effect and cause RTN in other colonies that have been in your tank for awhile. Try to get the alk back on track and the other levels should fall in line with water changes with new/better salt.

+1. if you are running probiotic system like pellets or zeovit, you alk should be around 7 anything over 10 dkh you will run into issues. I would get your alk and cal back to proper range and go from there, snip off the rtn sps frag it or what ever but try to get rid of all the other that rtn'ed before it begins a domino effect. best of luck, I know it sucks but just hang in there.
