Zoas not opening?

[Reggae Fish]

Zoas are starting to not open. All corals were treated before going into this tank. I don't see any zoas eating nudibranchs or eggs.

Water
Salinity- 1.025
PH- 8.21
Phosphate- 0-.5
DKH-7.0
Alk- 2.51
Calcium- 400
Nitrate- 0-2 (not sure I buy this. I'm going to pick up a new kit)
Temp- 80.7

All kits are salifert except phosphate. No corals are stinging them.

Any thoughts?

I have had some close up for no real reason and open again out of the blue.Sometimes they would stay closed for days,not really sure why but i did have a colony suffer zoa pox and lost the whole colony I think it was from a rapid temp change

Some are finicky. I had a problem with flat worms. Didn't really think it was a problem at first. I had them before I had zoos. They seemed to, over time, take a toll on the zoos. Nuked them and all is better now.

give it time i would worry after a week of not being open

Still not open. All water testing out. I'm looking for the stuff I treat them with. It's not lugals. I think it's made by seachem. I'm looking though.

All my zoas. Orange bam bams, dragons eyes, eagle eyes, etc...

Any thoughts?

In addition, I don't see any pox but that all the frags/colonies are spread out throughout the tank and are all affected.

Still no sight of nudibranchs

can't think of any reason but i can tell you i can keep zoas in my 29 gallon under t5's and in nano cube but they don't live or do well in my 125 gallon for some reason. Couldn't give any explanation they do fine in 2 out of 3 of tanks, and everything does fine in tank but zoas and some lps corals.

is there a difference in lighting


i had a hard time keeping zoos with t5 until i changed the bulbs to a more bluer look ---less par

I only kept a few from my other tank. Some came from friends. Some came from the store. All were doing great...until the day I posted. I've never had an issue with zoas except the nudibranchs so I'm a bit confused that ALL of them are affected???

I believe I found a Zoo eating nudi on my glass yesterday. My problems is I cannot dip most of my zoos because they are attached to huge pieces of rock.
