Torch skeleton

[dylanst.onge]

So I have a colony of indo gold torch that as slowly receded over the last month or so and seems to have spots on the skeleton now but it is still alive but not doing to great. Have dipped in everything and found no pest trying a light iodine dip tonight and going to see what happens anyone seen this before?

Maybe water quality

Salinity 1.026
Alk has jumped around alot lately after switching from tropic Marin balling method to Triton cor7 now it's at 8.2
Calcium 420
Mag 1380
Phos 0
Nitrate 0

All other torches,hammers,frogspawn, sps and everything looks fine

If it got to high that could've definitely been the issue. I was using RS coral pro and my all was up around 11+/- had a few issues myself.

It wasn't to high it went to low lol dropped to like 6.4
