I have a small zoa rock that has hair algae on it but I can't rip off the algae easily so I was hoping to get a solution to this problem. I know I can't get a tang unfortunately to eat the algae up. Here's a pic any help greatly appreciated.

Look in to Hydrogen Peroxide dipping http://http://www.reef2reef.com/forums/zoa-discussion-club-zoa/40552-dipping-zoanthairans.html
I dipped my zoa frag plags before to get rid of hair algae with good results.
Just make sure to follow the instructions
