Polyps won't open

[cgarsmokr]

I have several frag of zoos that opened at first but after a couple of days they closed and haven't opened since.
I have 6 t-5 lamps so I put them low in the tank and have 5 layers of window screens to acclimate them to the bright light. Yesterday I did a lugols dip as per Mucho Reefs recipe but nothing has changed. I don't know what's going on.
My params are right on target and I do 10% water changes every week.

they might not be getting enough light?

Look at night to see if there is anything crawling and eating them.

I dont think you would need to acclimate them to that lighting. Sometimes they take a while to open up after you dip them, so give them some time.

I haven't noticed anything eating them. The polyps opened up when I first got them and then began closing. It was then that I got the window screens to acclimate them upon suggestion.
Sorry for any confusion.

same thing has happened to a frag of Bytors I got recently. Opened the first day and have been closed since, all params are good, 37 gallon tank with 150 Watt 10k HQI DE bulb so I think light is good as well.

I know. These zoos sure are temperamental . One of those frags was Eagle Eyes and I really liked em but I don't hold out much hope. They, along with a few other frags are closing up and shrinking. I think they're goners.
