Soaking in Vinegar/Water might loosen it up. (couple days)

if it's dead, you may as well sun-bleach it. i realize it's not the best time of year for that....but it's proven very effective for me. and most importantly...it's safe.

yai guess ill have to wait for the sun to return to do that would a 100% vinagar bath work?

Vinagar disolves calcium.So if you do it becarefull,you wouldn't want to get up the next morining and find a pile of mush.But maybe it will work to disolve the outside layers with the algae on it.But I think after you would want to put it in fresh water to dilute the vinagar that seeped into the holes in the rock.Plus the vinagar will act as a carbon source for bacteria,will be a good kick start for your cycle,but make sure you do a water change after cycling.It may cause a large bloom and use up all the oxygen.
