Is this part of the rock, or something growing on the rock?

    After over-lighting my tank and pretty much bleaching my live rock a few weeks ago, the color is finally coming back in. However, so are these brown spots. I'm concerned mostly because each one appears to have a small hole in the center. Am I being too paranoid about my rock, or is it something more significant?

    Its probably the start of algae. Also the rock turned white because you exposed it to air, not over lighting it

    Really? I have a BioCube, and the hood is rarely open... The brown spots are also hard. Shall I just continue to let things be?

    No, when you put the rock into the tank you had to expose it to air, that will cause it to turn white
