How long for algae to overgrow coral?

[AC1211]

So my LFS has been out of ideal cleanup crew for a while and I have some bubble algae and hair algae surrouding my LPS. My candy cane especially becuse it has algae the closest concerns me... if i can't get stuff for a week what will happen?

Any healthy coral should generally not be affected by algae
