Need help!

[Overlook Reef]

I did my weekly water change this morning and everything was normal.

Ammonia 0
Nitrite 0
Nitrate 0
Phosphate 0
Calcium 480

After a couple of hours my Xenia started to shrivel up like I have never seen before!

All other corals and inhabitants are doing great!

The Xenia is not breaking down, but it looks really shriveled up and one cluster is starting to look grayish and very limp!

Has anyone got any advice? I am going away for three days in the morning and do not want it to die and wipe out the whole tank.

Should I take it out or has some people experienced this before and did it recover?!?

Please help me make this painful decision!

Most likely something was different with the new water. Most likely it was mixed at a different SG compared to the tank. Usually the Xenia will come back after a few days. However Xenia is tricky, and can fail for what would seen a minor problem.
