Help Please. I have a 6 by 4 inch long very thin piece of hard coral that was dead. It has a few feather dusters living on it. I have been using as a bridge from one live rock to another. About 6 weeks ago it started having hair algea grow out of it. I would like to keep it in the tank. I heard I could soak the piece in clorox to kill the algea. I am worried about then putting it back in the tank no matter how good I rinse it off. My questions is will this get rid of the algea and be safe to put back in or should I just throw it away. Thanks
