Pulsing xenia losing color within hours and acting sick

[lil.guppy]

My pulsing xenia has been growing like a weed!!!
Well this morning I turned the lights on and the main stock looks pail and its acting as if its having a hard time pulsing, but all the baby sprouts have good color.
I tested everything and the only problem I might see is that my calcium level was like 420 so I did a partial water change.
All my other corals are doing fine.

Just wondering how long have you had your pulsing Xenia?
I've noticed mine sometimes close up kind of like a Feather duster, tight as a ball.Then they open back up and pulse again.
How are yours doing,now?

Mine is GREAT! Growing like a weed. I will have to get some updated photos. I moved it to the middle of the tank versus the bottom and its doing even better.

Glad to hear they are doing well!

I like to put mine near the bottom of a rock ledge and watch them climb to the light.That is so cool!
