    Ok, so some of my purple corraline that was growing seems to be turning white in some places. I doesn't look like it is dying, it is really think white and a nice milky color. Is this normal, I am kind of concerned. All perams are fine and have been since forever. Has anyone seen this before or is there something I could be missing? Thanks!

    Coralline comes in a lot of different colors. You're lucky, I'm trying to figure out how to get mine to do that.

    magnesium, calcium and alkalinity levels being depleted is one of the main causes of coralline going white

    as is pouring boiling water on it when cleaning a power head etc - that also causes the coralline to die off

    exposure to air will also do that, live rock out of water for to long will result in the rock turning white when placed back in tank

    if the parameters mentioned above are corrected , new coralline will encrust over the white stuff

    Mine did that and then after a week or so turned purple again. I don't know why...but it's fine now! It might have been exposure to air, as I had recently brought the pieces home from the LFS.
