Encrusting Gorgonian not opening

[blakefoster]

Hello All,

I have two different encrusting gorgonians in my 125g reef tank. Both of my encrusting Gorgonians are not opening up in the day time like they used to. All my other corals (Acans, hammer, frogspawn, GSP, blastos, galaxea, montipora, pipe organ, zoa's and many other) are thriving. I cannot figure this one out. You will see in the top left of the pic the e.g. I also posted a FTS so you can see the other one on the bottom-mid right to the right of the hammer. The white mat is not eroding so i don't believe it is dying, just unhappy i guess. I have a a 4 bulb T-5 lighting system. Water Parameters are:

PH: 8.2
Salinity: 1.025
Nitrites: 0
Nitrates: 0-10 (10 usually at the time of a needed water change)
ALK: 11
Calcium: 480

Any ideas i could try or knowledge y'all can share would be much appreciated!

How long have they been closed ? And how much flow is on them ? I have two sections of my reef tank covered with these same corals . There has been times when they dont open for weeks and tjey get a film on them that im thinking is kinda like what leathers do to clean themselves off as they grow ove noticed that after the film peels off and they open again tjat they have growen more when i first got my first piece of this it didnt open for almost a month i was about to toss it than decided to move it into more heavy flow i meen alot of flow right in front of one of my korilia 750s and two days later it was opened . But these corals do this off and on sometimes its a day and the film is gone and they r huge and sometimes its weeks . Im not sure if theres something that triggers it or what but ive had these corals for a long time and and they r very healthy and have grown alot so I know that theyr ok . Maybe someone else can help add too thise. But these r my expiereances with this
