dead coraline algae

after my move across town the beautiful coraline algae growing on the back of my tank has turned white. I dont know if its from the move or the fact that my lighting has been inadequate for a coupla days. my real question is two-fold:

-will it come back or is it dead?
-if it is dead, do i need to remove and what is the best way to remove it?

I assume the coraline dryed out during the move.I'd scrape it off.

It should come off pretty easy

+2 yote

yep the top inch of mine died every time i cleaned my tank. but always came back.

It's dead. Even if it's exposed to air for only a little while, it will die. It's fine though, it will come back in no time.

During a water change I keep the coralline that's out of the water wet using a turkey baster.
