Knowledgable Zoa/Paly People I'm Calling You OUT!

I am inclined to think that when alk drops your Ph is allowed to swing and that may be a factor with zoas.

Andy, thanks for going the discussion. I am correct in stating that you're saying the pH changes (a result of alk drops) are a bigger issue for zoas than the drop in alkalinity? Interesting thought. Does anyone know how much dripping Kalk impacts pH? Wonder if we might be able to tie these together to support or refute thoughts on Alk or pH changes?

I have seen this zoa "shedding" before. Especially on newly imported zoanthid colonies. I assumed it was stress and shipping, causing the zoanthids to shed some mucus. Possibly due to lack of light for 24 hour period, in combination with poor water chemistry?

Other than that i believe the fragging of zoanthus/palythoa colonies into tiny frags might cause the same level of stress for the animal.

yup the fuuny thing is this piece I was referring to was a newly acquired frag from a buddy's tank...so maybe the stress of moving it into my tank caused the "shedding" to occur?

all the tissue underneath where the skin "shed" away all looks good and new, almost like it was a way for the coral to cleanse itself

I dunno maybe I am crazy and just seeing things but I'd swear LOL

Well based on other posts I would say that you may be on to something here. Guess I'll have to pay a little more attention to mine in the future and see if I notice them shedding. Anybody notice this response when doing water changes? I've noticed that a number of corals (including some palys) will slime in response to water changes.

yes, all my acros slime when I do a wc but never noticed any of my z's and p's slime up so I'm not 100% sure what caused the "shedding" that I observed, that particular zoa has yet to open btw

I also want to add that 3% hydrogen peroxide will definitely wipe out any nusiance algae from frag plugs

Keeping my fingers crossed for you zoa. Good to know on the hydrogen perioxide, I've seen a fair amount of discussion on the topic, but never seen anything conclusive for sure till now.

Thanks I'm hoping it eventually opens, it hasn't melted so that's a positive LOL and it's the JF Bloodshot too! uggh :-(

yeah, I did 50-50 tank water-hydrogen peroxide
