What is this green Algae

[connectionzman]

Im about 5 months into the hobby and I have a JBJ65G tank that’s been set up for about 2 months now, at first I got brown algae all over my rocks and now I’m starting to get green algae, it’s not hairy at all what’s causing it, is it the precursor to coraline algae

Any help would be appreciated
