Question

Green circle So fot about the past 3 weeks I have noticed these green circles growing on the glass in my 55 gal saltwater tank. They almost look like the insise of a tree when they are cut down with all the rings. They come off pretty easly when I clean the class but they just keep growing back. Any Idea I have included a picture.
