Zoa issues

[Best Fish-Jake]

I have a 30g mixed reef that has been up for nearly a year. The tank is heavy LPS with a large zoa rock and a few sps pieces.
My zoanthid rock has had immense growth, but for the past 2 weeks, nearly all of the blue variety are closed and appear to be slowly melting. All other zoos are doing fine, and nothing has been changed recently in the tank.

(A hermit crawled all over my red's before the birds eye photo)

This image was taken before they closed.. I can upload new pictures in a couple hours

The only reasoning I have for this is that my yellow polyped zoas have recently encroached on the blues.. would a territory dispute lead to the entire colony closing?

Here's another pic of the rock days before the problem

Here's the problem

I don't see allot of white spots so it doesn't look like zoa pox's. if you can get the zoo's out I would dip them.

Dip them for what? I don't want to do that unless absolutely necessary, as I'd have to dip the entire rock that it's on.
You think something might only target a specific species of zoa and avoid the others?

I used to collect allot of zoo's until one day my zoo's got some type of disease that looked like zoa poc's. The polyps would almost close up with an opening in the top. It started with one
colony and then spread across allot of my collection. From what I remember it started with my deepwater zoo's. There were some colonies totally unaffected. So from that. Yes I think
that some issues can happen with certain species of zoo's. Yeah I understand you not wanting to dip the whole rock. Hopefully someone will have an idea. I have my fingers crossed for you.

Have you looked for pox? you should see it clearly. Looked for nudis?

Negative for nudis.. I only see 3 semi questionable dots on the entire 40+ polyp colony

It’s been quite a while.. forgot to update this thread[emoji28] everything is well

I think you need to be giving us some pointers.

Lol! Everything has been doing fine except for some discoloration with my sps.. I’d probably have to chalk up this growth to more frequent full-tank feedings and clean water. (the zoos seem to respond to Goniopower by Justin Credible)

Did you have an alk swing or salinity swing? Feel like zoas are very sensitive to those.

Those also could be your coloring issues on sps

Actually yes on the alk swing.. I Use coralife salt (which has a lower alkalinity) and I have been dosing ‘aquavitro ph 8.4’ for the last few months.. I currently manually dose whenever I do water changes/ top off.. when I had those problems with my zoas, I don’t think I had such a consistent dosing schedule. I havnt been testing my alk too much recently but I’d be willing to bet that it still rises and dips a bit more than it preferably would.

You think the sps would be better off with a consistent low alk (prob between 6/7) or with a higher alk but with more swings?
I’ve recently been attributing the faded sps coloration to having close to 0 detectable nitrates (which I can’t raise for the life of me.. turned off my skimmer and everything[emoji28])

I would honestly get you’re rate of consumption of alk and get a cheap doser. It is a good investment. Corals do best with consistent numbers. What I do is aim for a salt that matches where I want my values so when I do a water change they stay really close to near my tank value..

Thought I’d share this pic too
