This stuff is a fark green, has leaves on it. Really hard to pull off. It is taking over my live rock. And killing some of my corals. Any help would be appreciated.

Got a pic? Does it look like a fern or is it just a leaf on a stem. It sounds like either bryopsis or capulara to me but without know which it is I cant help you get rid of it, What are your tank parameters and Lighting?
