WD Polyp Bailout-help!

[ianryd]

After a chemiclean treatment for green cyano accompanied by 48 hour lights out my Walt Disney is not looking good. It is losing polyps and the skin is looking brown. I noticed this before I did the WC. All my other acros and corals look fine. I did experience a nutrient spike-I believe it was after the water change when I vacuumed the sand bed. Other params are ok. I started gfo, and am making water right now for another WC. But is there anything I can do for this acro? Should I frag the one good branch? Put it in my other tank?

Info about the tank-150 gallon. its about 6 months old, but everything was transferred from a 2 yo tank. Tank params are listed in the pic. First set is before the chemiclean and water change, second is 24 hours later.

That would be RTN, likely to to the multiple stressors of the spike and lights out. The side where there are no polyps has sloughed off the flesh. The coral can recover as long as the live tissue on the other side does not die off. You could cut off the dead portion and apply superglues at the edge of the live tissue to see if that stops it. It's a sort of super glue band aid. Unfortunately the prognosis is not good when it gets to this point.

Ok thank you. I'll frag the good bit. Hopefully I can save it.

If you are able to keep an eye on it throughout the day, I would wait to frag it. Sometimes the tissue loss will stop on it's own, and if it does, it's less stress to the coral to wait to cut off the dead portion until you see some re-growth. If the RTN continues at all then gut & glue right away.

Did the rtn happen before or after the gfo?

Unfortunately I have to get to work, and I just watched 2 polyps bail out in front of me, so I just fragged it. Got 2 little nubs. The rest was pretty dead. Fingers crossed! This coral has been a good grower so far, hopefully it can rally.

Rtn started before I turned GFO back on. I've been running GFO in a reactor pretty consistantly for about a month and it has kept my PO4 around 0.02-0.04. I took it offline for the chemiclean treatment, and just turned it back on today when my PO4 tested high.
