Not sure what to do?

[surfnsalt]

Stn has struck two of my sps and I think it's due to unstable alkalinity. Alkalinity was steady at 8.5 for months but then started to drop to low 7s (no signs of unhappy sps but I was worried so I upped my doser a few mls of 2 part b ionic. Then over like two weeks my alkalinity rose to 9.5. I backed the doser off a bit a few days ago and today I'm at 9 with Red Sea kit and 8.5 with salifert. I noticed stn on my green slimer two days ago and broke the one branch off that it was on and now today I see it on my bonsai not sure what to do next I know I need to keep monitoring my alkalinity and keep it stable anything else I should be doing? All other sps seem ok. 60gallon hex @ReeferMaddness843 @aaron23 @Diesel

I believe the alk swings are what caused this. Sps is very sensitive to that, keep the levels stable at where they were before and they should recover.

I just went through a similar event. Will stn stop in its own? I have a small area on a green slimmer. Should I cut this area off?

In my experience I've never seen it stop on its own but I'm fairly new to sps.

This may sound dumb but honestly it sometimes stops, but sometimes it doesnt. Best bet is to cut off the affected area and make sure to keep your alk and other parameters stable so the coral can being healing.

If you can remove the coral and place it in container. Then put some Lugols iodine it the container you want to have a tea color to the water. Stir the water and let the coral set in the solution for 10 minutes. Cut off the bad branches. If possible I cover the bad area with epoxy.
