    So I have this mall colony of green zoas(~50). The problem is that they are turning brown in color and I donot know why. Also some have the centers turning whitish.

    All other corals in my tank seem to be doing fine(including other zoas)...

    Those whitish dots sounds like you have either a fungus eating them or some nudi's. Are you dosing anything in the tank? Like Kalk? Luna

    The only thing I add to my tank is Ca, Mg, and buffer.

    Try a FW dip with Iodine for 10-15 seconds. Luna

    if they are new, zoos often change colors under different lighting.
