They require slightly different methods of control......first you have to correctly identify which one you have. Do a online search on each type or better yet post a pic here. You may have to resize the pic due to size limitations.

Cheers,
 
Looks like you got a really bad case of GHA. I would take it out of the tank and replace it with some clean purple coraline rock and make sure your water paramters are in check before doing this. After you replace rock be sure to run carbon.

This will be your least expensive route.
 
yeah. i ended up getting a larger aquarium and getting a yellow tang. im pretty sure he's the one that cleaned it up. the rock looks great now.
