    Hi All,

    Took all the advise you all gave me and put a 150W halide in the tank along with the t5s and t8s.

    In the 2 weeks since I put this in I have noticed that my live rock is getting some pure white patches.

    Is this some sort of calcium buildup or do you get white coraline algae?

    Is it possibly older more colourful corraline that is now dying off? most coraline in my tank flourishes in low light but dies in brighter light...

    Could also be a deficiency of calcium and magnesium.

    is that even possible with a 20% waterchange once a month?

    Light shock... or exposure to air for a prolonged period of time.

    it seems to be only happening directly under the 150w halide.
    not on the darker side of the tank

    No probably not. Could just be the intense light.

    No Problem, its just nice to have the colour of coralline algae in the tank but without the correct lighting you may not get corals to grow. To me, coral growth will always be the determining factor in my tank.

    SaltyReef, it is a light issue that is burning your Coralline. I suggest raising your light a bit so your corals can acclimatize to it, then slowly bring it down.

    i agree with mekaeel, metal halides are powerful and you can bleach corals if not acclimated properly but also the coralline will die off and another species will invade :)

    Hi All,
    thought I would post the results of this thread.

    What I thought was bleaching coraline algae actually turned out to be an urchin leaving his trail of devastation on the coraline algae.

    The upside is that the coraline has grown back better in my tank.

    I assume it's due to him grinding it up and spreading it around the tank.

    White Coraline Algae

    I have the exact same problem, and you have just confirmed my suspicion in this regard.

    [​IMG]

    I have been dosing with Purple Up on a daily basis and my Coraline Algae growth was doing well until my Urchin climbed into it for breakfast, lunch and supper. :tt2:

    So now, I don't really know what to do - i.e. Take the Urchin back to the LFS, or accept the fact that he likes Coraline Algae and just live with it.

    Your thoughts???
