It could be the white skeletons of died off coralline red algae that seem still around there. This happens often when the LR tank is a few weeks old.

I had this, too, and I read that the adaption to the new lighting conditions may cause this. My white plaques seem to be overgrown by the still intact neighbouring coralline red algae again.

Im also saying it's die-off. No biggie, it's part of the process.

ah ok thanks, i did change the lighting a few weeks ago so makes sense

Well whatever it is, it's certainly not white spot (cryptocaryon irritans)

Rocks are not affected by whitespot along with most if not all other parasites as they usually require a live host normally in the form of a fish to thrive!

that deof is die-off as near enough everybody I know has had it in there tanks one time or another, it is most common during cycling or under changes in lighting!
