Acro STN help

[Formulator]

I had an unintentional large Alk swing 2 days ago and am seeing this STN on one of my acro colonies. Everything else in the tank is doing well, including other SPS and another acro frag. Though I did lose one acro frag to RTN immediately after the large Alk swing. My parameters are back on target now. What can I do to save this colony from further damage?

It should pull through. Is the stn spreading?

As far as I can tell it doesn’t seem to be getting worse, but today was the first I noticed it. Hopefully it doesn’t progress overnight tonight… So you suggest just leaving it alone and it will likely recover itself?

I think so. Doesn't look too bad. If it continues spreading, you can clip below the white. Search about lugos

Maybe dim the lights some if it looks to have spread by tomorrow

Should recover but if not clip the bleach parts off
