Is coralline on old live rock still alive?

[daveverdo]

I have some old live rock sitting in a tank of saltwater for over a year. No heater, no circulation, pretty much untouched for quite some time. Most of it is bleached but there are a few pieces that still have some colored coralline algae on it. Is the coralline still alive or does it keep the color after it dies?

Put it in a tank and it should come back alive, mine did at least

From what I've seen, coraline algae is some tough stuff. I have a piece of LR that I keep in my QT and it has undergone numerous hyposalinity treatments, months without lights, and it still has coraline algae on it that grows once I leave the lights on for a while.
