What's wrong with my setosa?

[Proteus]

Mines in low flow med light. I would guess a little die off. Color could be better to. With as many different types of coral you may be running into a chem battle rather than sweepers.
IMO cut it back and run some carbon if not doing so

Color is a bit washed out in the picture. Its bring pink-orange in the tank.

I do run carbon (chemi-pure elite). So should I cut that part?

Ok good

Cut off the dead parts. What's the surrounding corals within like 6"

Preiously, there was a monti pokerstar, an acro, a stylophora and the chalice (which was like 6" below) and now, in the new location, there's magician paly, a green zoa and a monti confusia (or something like that; I can't remember the exact name).

I was thinking its either because of the chalice or because of the low alk. Is it possible to have STN due to low alk?

[Proteus]

Yep low stn I believe can be related to low alk

How low is it right now

SPS are sensitive to alk swings.

We notice STN if our alk drops bellow 6.5dkh.

Mine reached 5.4 before starting to dose haha. I have taken it up to 7.4 but every 12hours, I have noted that 1dkH drops. Ca remains 430-440 while Mg is like 1300.
