Is my coral dying?

[robhart60]

Hi,

I have this mushroom coral and have been having problems with it for about a week, and not sure whats wrong with it? I have had it for over a month now and it has always looked great! And suddenly its gone like this. (Pics below)
I have previously posted a thread about this but I have better pics now and was wondering if it looks normal or if its dying? Also any advice on what I could do to help it.
I have a fairly strong current in the tank but have since directed the powerheads further away from it, as I read that this coral doesn't like to be in direct flow. (Which hasn't helped it)
I did all water tests I could today and they are:

Temp: 26c
SG: 1.024
PH: 8.2
Ammonia: 0
NitrIte: 0
NitrAte: 0
Phosphates: 0 (You'll see on a pic I took when it was doing well that I had a lot of hair algae, which has now gone thanks to my RO/DI)
CA: 440
MG: 1200

I really need some advice and if this is completely normal or not.
Thanks for you time.

give it time & see what it does leathers do wierd things

mine closes up like that for a few days too. try slightly stronger flow on it. so long as no brown or black spots you're prolly ok

if i remember they need to shed every so often so they close up for a facial, its probably fine and will be back as perfect as can be in no time. What are you doing for the HA??

Mine does that all the time. It will stay closed up for like a week and then it's fine again. Sometimes it will close at night and sometimes it won't.
Did you test for alk?

Thanks a lot for your advice, I really appreciate it. I'm a complete beginner with corals. I do research what I'm buying but when something looks out the ordinary its always good to get some advice, so cheers.

Its been opening up less and less for a while now, when it first closed up for most of the day I decided to move the powerheads a little, I have now put them back to their original position. Weird thing was that a few days ago when the lights went on, it was very dark grey for a few hours before completely opening up. Then after the lights went out its stayed bold ever since.

What is "HA"?
And the ALK: 2.74 (Don't know why I forgot this)

I think HA is hair alge. and you already said ro/di helped.

Ohhhh yes of course...hair algae its long gone, at last!

Although it is probably just pouting/shedding, I would focus on raising the magnesium up a bit to around 1300ppm.
