I am new the the soft corals, and my first piece is an encrusted gargonia. Its been doing fine till this last couple of days. I have been having trouble with cyano so I added chemi-clean and turned the lights out for the recommended 48 hours. Well I did the water change and turned the lights back on and it has is opened yet. I did my water change this morning and nothing else has distrupted the tank. I even put in some DT's to see if that would help coax it out. Nothing, so any help will be greatly be appreciated.
