Anyone know what this is?

I have had this "growth" for quite a while on my live rock in my 29G seahorse tank. Anyone know what it is? It is starting to take over my tank. I need to get rid of it somehow.

That's it for sure. Thanks. Been researching it since your post. Oh Boy. I am in trouble. Does not sound like there is an easy solution.
