Well, the problem is that TODAY, your temperature is 814 degrees.
Just Kidding,

Looks like your Calcium is a bit low....You should aim for over 400ppm.

What was the temperature of the new water? Sometimes that can affect your corals.
Were the corals exposed to air when you changed out the water? Did you use RO/DI water? It's odd that this would happen "all of a sudden". You have done water changes before with the same process I assume.

Keep an eye, I'm sure they will come back....corals are very temperamental.

The calcium is a bit low, but with softies you do not need to keep your calcium over 400.

Your calcium is a little low. They sell solutions that could fix that!

 

[Bifferwine]

Yes, calcium is a bit low (as everyone else pointed out), but not low enough to harm the corals that you have. Softies and LPS don't NEED calcium at 400+ to do well. Calcium is not the reason why you are having problems.

What kind of water did you use for the water change?

how long did the new water mix before adding it to the tank? did you just mix it and dump it in or did you mix it let it set for several hours than dump it in?
