Do my Zoas have Zoa pox or something?

[Kaiser]

My Zoas have been acting weird lately and i have no idea why, i've been running the tank for about 6 months and until now my zoa have been the happiest coral in my tank, surviving everything. I'm worried about them, one is half open but not fully extended, and the other is closing weirdly during the day, i don't know how to explain it so i'll link a picture, any help would be appreciated

As you can see, There is a white spot on the side of one of my Zoa, and i thought it was just a growth but i'm not sure what it is now.

 

[Kaiser]

My parameters are:
Ph: 7.9 - 8.0 during the day, 8.1 towards the night (i can't seem to raise it any higher)
Alkalinity: 14.8 Dkh (it's been pretty high for some reason)
Nitrate: 0ppm
Ammonia: .15 ppm (ish)
Calcium: 480ppm
I recently started running a phosban reactor using Rowaphos. My pink zipper colony on the other end of the tank doesn't seem to be affected anything so i'm wondering whats wrong.

Is it a snail . Zoas will close when pests or other critters bother them . Where's the ammonia coming from it should be 0 . Is that an Aptasia I also see in the pic.

 

[Kaiser]

I'm not sure if it is aiptasia, its been there for a while, i always thought it was a hitchhiker zoa of some sort. I recently went fishless after an outbreak of ich, i was feeding my coral and my cleaner shrimp, could my biological bacteria have died off and that be why i have ammonia? (i was using a API kit so it wasn't very accurate if i've heard correctly, but i don't know of a decent kit and i only recently got the money for one.) On the other hand, i have trochus snails and blue leg hermit crabs, i've noticed some hermits bothering the Zoa previously but thought they were just curious, but that dot on the side never moves and seems circular.

Your Alkalinity is Crazy High.

Are you using RO Water?

Your Ammonia is High.

Your Nitrates are Too Low (I would Feed your Corals to Raise It) (Reef Roids Works Best).

What do you have for Lights?

What do you have for Flow?

 

[najer]

Have you got a closer / better pick of the large white spot?
How long have you had the zoas?
It could possibly be a sundial snail which is bad news.

I pulled the white thing off the other day, had no idea what it was, but it's gone. I'm using RO from the store I work at, I have 4 t5 (2 actinic 2 10k) I think my ammonia test might just be innacurate since I have pink zipper zoas on the other side of the tank and they are fine, I'm swapping off every other day from using Kent microvert and Kent coral accel, I have about 900ish gph throughout my tank, it's a 20 gallon nano with a sump/refugium. My alkalinity is high and I have no idea why, it's been like this for a while

I use Kent Lugol Solution as a dip for all my corals so i hope that handles most hitchhikers

My 20 Gallon has 1,450 GPH Between 2 Power Heads and I am Thinking about Uping the Flow.

Zoanthids Love Flow.

What Power Heads Do You Have?

 

[Kaiser]

2 Koralias. Could it potentially be lighting? i noticed my hammer coral starting to close up earlier this week, its not closed, but its not as extended as before. Plus the frogspawn i got that i thought was finally opening up appears to have closed off and be dying. Maybe my bulbs need to be replaced? i got a used hood and didn't replace the 10k...

 

[Kaiser]

My flow seems to have been fine the entire life of the tank, and only 2 of my Zoa have recently started freaking out...

 

[Kaiser]

I do have a outbreak of hair algae but i'm dosing tech m and the algae is on the same rock but not right next to it

 

[Kaiser]

Turns out my salinity was somewhere around 1.03 for some reason, at least according to a local store. Let's hope I can still save my coral by lowering the salinity

Any news, how are things now?
