Red Bubble Algae or Red Grapes?

I've been told this is red bubble algae. But does bubble algae branch like a vine of grapes? Could this be young red sea grapes (Botryocladia uvaria)?
They have stems, and one of the strands has a bunch of bubbles/grapes on it. These things are spreading like crazy and quickly over the rocks. I'm clueless because of these things are individual bubbles which makes me think its bubble algae and some are strands which means it could be red sea grape? I'm trying to ID this stuff before I scrape it off or get rid of the LR completely. Maybe I have both on the LR? Help! thanks!

I don't have experience with the nuisance red bubble algae, but I do have a lot of experience with the desireable red grape and have never seen it present itself all over the rock like that. Now, there are many variations of algae out there... I've just never seen it with my grape in any of my tanks.

yeah it spreading all over makes me think its red bubble algae, but the branching stem on it is throwing me off. maybe the branching stem is normal for RBA...im new to saltwater, i dont know the differences yet. Thanks for your input Cranberry...

I'm honestly gonna guess nuisance red bubble algae. I'm going to have to get hold of some rocks that have that to learn more about it.... it seems pretty "popular" lately.
