How to get zoas to open again

[Ocean’s Piece]

So I have some corals that have gone through a lot over the past 2 months, especially my zoas. The first thing that happened was I added additional lighting. I made the rookie mistake of increasing too much too fast and my zoas and some of my other corals did not appreciate it. Then, about a month later, dinos. Everything was mad. Fortunately, I beat it about a week or two ago. Things are starting to look a lot better, but there is one zoa that hasn't opened any of its polyps in 2 months which is concerning. Three of them are opening, but still a little closed and not fully extended. One of them, which I got a few days ago is perfectly happy (as of now at least). Is there a way to get the zoa that hasn't opened to open and is there any way to get the other zoas looking back to normal? Is this a matter of time before things start looking better on their own?

You need to figure out what is not making them happy in your tank and then they will be happy and open up.

Place them in a shaded area and give them a peroxide or iodine dip if needed

Pic 5: New Zoa that is fully extending

Can anyone tell what’s going on from the photos for I can treat correctly?

Can I dip these in Revive? Also, what about the ones that have encrusted off the plug, how do I remove those to dip?
