try moving it to the bottom of your tank in ambient lighting and see if that helps:):) i believe you have some light shock happening plus the move to a new tank:)

Hmm, too bad you can't find a water report. Here's one from Greater Vernon. As you'll see there are some things in there that we actually need in our tanks such as calcium & magnesium. But there are also traces of undesirables that are just too risky IMO to keep feeding into my tank year after year. Come to think of it, I don't really even want to drink some of that stuff myself, even though according to the authorities it's at safe levels. I've been using RODI water for my tank for well over three years now & tapping off RO water for coffee, tea, drinking water as well. Great investment.

Testing for the standard parameters like nitrates, ammonia, phosphates, pH, calc, alk etc. is all well & good, but we don't generally test for copper, arsenic, aluminum...... so saying everything is zero is fine, but what about all the goodies (nasties?) you can't test for?

lol holy ****. I see what you mean by not wanting to drink it, sure its at low levels but still, arsenic, mercury? MAN!

So if I got this right it was in another tank with PC light and unknown water parameters, then they were moved to another tank after they started to close and they have not open yet under the T5 and new water condition.

That's a lot of things to adjust to for a healthy coral, even more so for a sick coral...they will need time and a slow acclimatation to the new light.

They might come back, they might melt..hard to tell. It will probably take some time to come back if it does.
