white chalky substance

I have a what appears to be a white chalky substance growing over the purple algae on my live rock. I'm sure it shouldn't be there. Can anyone offer some advice?

can you give us a picture? That would help a lot!

Its probably bleached coraline algae. Its not growing, your coralline is dieing. If this is the case, don't worry, it'll come back.

I was wondering if it's the algae dieing. Is this a common occurance? I'm afraid I can't get a picture out just yet because my camera just broke.

if you just put sand in, it could be fine sand dust settling...
