Zoas closed/melting/dying please help?

[DrewL]

Super Saiyan Zoas closed up on Saturday, 1 bigger polyp seems to be missing/retracted back into the mat, the 2 you see open haven’t closed up all the way but the mouths look pointy? I don’t know what’s wrong, my parameters are good & my other 2 zoas & Duncan are currently thriving

Tank looks pretty new.
What's your lighting and flow?
What exactly are your "good" parameters?

tank is few months old (after cycle)
I don’t know the exact light specs, it’s the stock coralife biocube lights, they are 100% strong enough, these zoas get the most light out of all other corals, the lighting and flow is not an issue.

Parameters:
Temp: 79
Salinity: 1.025
Nitrates: 5 ppm
pH: 8.2
Alk: 11 dkh
Calcium: 380 ppm
Phosphates 0.1 ppm

How do oyu keep your ph so high in a biocube? I was looking into one or a fluval 32 aio with closed lid but I am worried because I cant keep ph over 8 in my open tanks and I heard closed lids lower ph and if your tank is new I am sure your not doing kalk. yet!

Alk is high and calcium is low.

Do I see dino starting to form ?

Alk- 8-11 dkh
CA- 400-440

I don't think they're necessarily dying - just a bit ticked off. Sometimes this happens when something crawls over them, etc.

Alk isn’t high til it’s 13 imo
Cal is a little low but 380-400 is fine for softies

and not Dino at all. Just a little brown algae my snails take care of, still got new tank uglies

Not sure lol I point the powerhead straight up so there’s a lot of movement and I leave the food door open most of the day. I’m steadily at 8.0 - 8.2

I will just share my recent experience and hope it helps you. I introduced a Zoa, a blue polythoa, duncan and a mushroom as first corals in my tank. The Zoas didn't open, duncan was small bloom and mushroom died. The water parameters were fine - Ca around 450, Mg - 1400 +, Alkalinity 9, nitrates under 5 ppm and Phosphates 0.02. An experienced buddy said that due to stress of change, the polythoa is releasing toxins in the water impacting other corals. Advised a 30 % water change. Seems to have worked for me. All Zoas have opened and bloom size of duncans has doubled.
