nuisance or normal?

I have these red clusters popping up around my tank especially on my tonga branch....is this something that needs attention or is it normal?

Is it the macro algae Dictyota? There is not contrast to the images. Is it Cyanobacteria?

Then looks like Red Dictyota, just google it. I have had it in the past show up in limited areas, the algae never became invasive but I have heard that it can. I am not sure what eats it. If this is a new systems you might be able to go the hydrogen peroxide route.
