Hi all, have started to get this red algae building up on rocks, wondering what it is and should I be worries

Looks like cyano bacteria. It's considered a sign of elevated phosphates/nitrates. You can remove it manually pretty easy and increase flow to that area to prevent a return. I would test the water before taking any other actions as there are dosing options. It is bad if it grows over the corals.
