Zoa turning inside out

[Ksturg]

I started using gfo cause I had a Dino outbreak real bad...so I lowered my p04 and stopped skimming and raised my n03 to 5ppm by feeding more heavily it killed off the dinos but now this. It’s only 4 polyps out of about 25 so I’m not real worried yet but I don’t want it kill off my whole colony what ever it is.

So the four polyps that has the stuff coming out of their mouths I lost they are real small and receded on the rock

Thinking back, I remembered I had lost some Radioactive Dragon's Eye's 2 years ago that did almost the exact same thing, folded out like an umbrella, puked brown crap, shrank, then melted. No idea why, but I've not had much luck with zoa's in this tank anyway. I took one last chance with some Morninglories from AD in Feb, and they seem to be holding on, but they sure aren't spreading. I've about given up on zoas.

I wonder if this is bacterial thing - Leather corals do produce antibiotic compounds so might not be a bad idea to add one if you don't already have one? https://www.sciencedirect.com/science/article/pii/S1658365516300073

I have a lovely little Devil's Hand sitting in one corner, so if it's putting out antibiotics it ain't helping the RPE's.

Well I think with the dinoflagellate die off I had a bacteria bloom and that may have caused it. It only affected 4 polyps out is 5 different colony’s so I guess it could have been worse.

My two giant colonies of gsp haven’t opened since all this has began either and they are still closed.

I’ve got a similar problem. Don’t know how to describe it other than turning inside out. Others not just closed, but inverting. Worried this is the end. Other colonies are fine.
