What could be wrong with these zoas?

[MellowReefer]

Can anyone guess what's bothering my zoas? A few weeks after I put them in my DT on the sandbed they started stretching out so I thought I should move them into a higher light area so I moved them under more direct light and a few inches higher but it hasn't helped and now some of them aren't opening at all. They all came on the same rock but the ones that are stretching came with a slightly different color than the ones that still look alright. No whitish stuff or any bugs that I can see.

Also worth mentioning, when I first got them they had some type of fungus or zoa pox and I dipped them several times and it went away, and they were looking perfect for over a month in my quarantine tank so I moved them into my DT and they were fine at that time. In my QT I had T5 lighting, now they are under LEDs.

Thanks so much if you can give me any advice on what to try next.

adjusting to your tank environment. What's the parameters on your DT? what light were they under previously compared to now.

Salinity 1.025
Temp 79
Alk 9
Cal 420
Mag 1440
Nitrate 0
Phos 0.05

I have other zoas doing well all over my tank.

I am running AI Hydra LEDs on my DT. In the QT they were under a dual T5.

What's the intensity on the hydra?

Were those polyps stretching when they were in the QT?

No, they looked great in QT under the dual T5 light.

My Hydras peak intensity is 20 white, 80 blues, 7 red/green, 40 violet, 15 uv. This is based on reading the Hydra settings thread and seeing what most had success with. And my other corals seem to like it and are growing.

I recently took down the QT with the T5, otherwise I'd throw it back in there and see what happens.

I might put them in my other small tank with brighter white LEDs and see what happens in there.
