    Lack of Ca and Alk is one.Change of lighting (more intense lighting) is another factor. lets here from some of the Gurus

    Spot on Miki, the coraline starts to turn white if there is a lack of light/too much light (bleaching) or Ca depletion.

    Air exposure always seems to work as well...

    I did quite a big water change a few days ago with lights on. The coraline higher up is mostly affected, so sounds like a combination of both air & light. Thanks guys :)

    I guess the coralline was exposed to the air for a long period of time.

    My coralline goes white when it has been feasted on by my rock urchins :thumbup:
