zoanthid's slow down down gone!

What do I need to look for way they are going away?
They were growing very well then some are ok and some dying away.
Looked for but see nothing on them eating them.
I did not do any changes for water additives.
Water numbers are the same.
Lighting the same.

I read the other threads on dying off.

Also as they said on the other posts as dip the zoo?
But if it on a big rock what do you do?
What is there to try?

Stray voltage? Not sure just throwing out ideas. What are your levels at? (pH, Alk, Calc, Etc.)

 

[fishtk75]

I have ground probes.

ph- 8.2
cal - 400ppm
alk - 3.30
Nitrates - 30ppm
nitrites - 0
ammonia-0

Tryed to do pics but can not get a closeup that you can see out of focus too close.
the zoos most are closed up and die then.
no white stops or poxs as other members said I see.
