Wondering what these lighter spots are- bad bacteria?

Anybody-
I'm noticing some lighter/ white spots on some of my rock-
I haven't added anything but some copepods so I'm not sure where it could have come from... Should I remove the rocks?
My fish seem fine...
Help :/

Im not sure what white spots your referring to, tough to tell, but white spots in the middle of coralline growth is dead coralline. But, coralline will grow in different shades also, could be light pink to dark purple.
