    +1 on cyano. what your n02,po4 levels at? can you give us some more parameters. how much flow has it got?direct,indirect? also,you dont have to feed it. What I can see is that your nitrates,po4 are a bit high.feeding reef snow will add to your bio load and can quickly add to a nutrient increase and cyano,gha as you are experiencing. but more water parameters will help,also,what kinda lights you have?

    A Beautiful place!

    NO, you will kill all the bacteria and life on the rocks. Read the links @belindamotion posted on cyano. When you do a water change, you can siphon it off with a pipe, don't blow it all over the place.

    Is your alkalinity in degrees hardness or degrees meq?
    Is the coral covered with a slime like coat?
    The cyano developing have multiple causes. See the threads Belinda has attached
