    Possibly due to too much light. Were the rocks out of water for a length of time? Are they new live rock added to your tank?

    The top row of rocks in my tank, the thops of those rocks, are also white. I'm pretty sure in my case it is because there is so much light up there. As far as the rest of my tank, coraline is growing well. I'm curious to see where this thread goes :)

    How big is your tank, got a pic? How far is your lighting from the rock in question. How long is your lighting cycle?

    Best wishes :)
