Help. Blue Cespitularia Dying

[bobcoleman]

My blue cesp. came in fine when i bought it a couple weeks ago. It had good flow...but i wasn't sure about the light. So it thrived for 2 weeks, then the polyps totally closed and the branches sort of shrunk. I asked my LFS and they told me it was probably because the light was too weak. So i quickly bought an HO fixture... This made my aquarium brighter. And i fear my coral has suffered some sort of light shock.

Now, a day after the light change, part of the coral base has come off and the coral is ripping itself off my rock. My polyps have shrunken even more and my stalks are just so skinny. Its going to die!!!

It probably can't be saved now. But i've heard people saving the polyps so a new colony grows?
Are my water conditions horrible? I have no idea what caused the coral to die other than the light.

My ammonia, nitrates, nitrites and all perfectly fine.
Phosphate is near zero because i have phosphate remover.
Alk is at 9-10
Calc is at 500 (a little high)
Temp hovers between 76-78.
Salinity at 1.025.

WHAT COULD BE WRONG???

I have a brain in there too and it seems to be doing fine...unless its going to die soon.

Ill put pics up soon.

Happy from before:

PH? Any swing from night to light?

From my experience it's usually quick alk shifts or nitrates over 10. I would double check your results.

My alk is extremely constant as i rarely even have to dose it. It always stays as one value because i am not even close to moderately stocked. Nitrates are a tiny bit high but should be perfectly fine now. And i've just started using a chaeto refugium with night light on and day light off so pH should be fine. It's getting a bit better now, but all the polyps are still closed.
