Red flourescent algae or something else?

Hello everyone, been a while since I made a post because nothing has really come up until recently.

This has been growing in my tank over the last few days and I'm really not sure what it is. Anyone want to help me out and maybe give some tips on how to get rid of it safely with no QT tank

It's really red under the lights but more of a greenish brown color with no lights

Cyanobacteria. Vacuum it up.
