STN... Should I start fragging this one?

[Jwils27]

I have some SPS that are bleaching from the bottom up and I need advice. Basically should I let it be and see if it heals or start breaking it up to try and save some.

I had my tank go out of whack about 2-3 weeks ago. My temp went up to 83 my P04 reached 1.0 and my Ca dropped to about 350. I was on vacation and got lazy so now I am playing catch up. My Pink Lemonade, Blue Tort and Pearl Berry started to STN from the bottom up. The PB stopped, The tort seems to have slowed down but the pink lemonade is not doing great.

What I did so far: Multiple water changes, ran phosgaurd for 4 days and checked levels multiple times per day and slowly adjusted to what they are now.

Ca:440 (serna)
Kh: 7-8 (serna)
Mg: 1380 (Saifert)
Temp 77
Salinity: 1.024
PO4 .25 (serna)
NO3. 10 (serna)

I have lots of other SPS doing great. I attached tank pics to help. Thanks in advance for any help.

I would at least get a backup frag or two.

I’ve experienced similar cases where some corals would stn while others are fine. Most likely the stn will spread to the rest of the colony it’s just a matter of time. It would be best if you can cut off the good portion and remount to save it.

Frag the good parts asap.
