What kind of algae is this?

Im not currently able to check my parems because I havent ordered a kit yet but I was wondering what kind of algae this is? It's a light green but pretty dark in the center and currently I only have 2 or 3 small patches of it on one of the rocks, I just checked on it again and it's still the same size that it was six hours ago so I don't think it's something serious but Ive been wrong before lol. I've only had this up and running for a day, I tried rubbing it off with a toothbrush and scraping it off but it's literally crusted on and has a really rough texture, so its not a slimy film. I'll post photos of it once the water is actually clear. I did use sand from an already established tank.

Do you have a light on over the tank? Mostly likely just an ugly stage. Is that correct you just set the tank up a day ago?

I just have a basic 6500k LED currently because it's a 5g bowl, I have a nook underneath my desk just above the storage space that it's on, there's a slight overhang that goes over the bowl (it's about 1.5ft) I'm going to be installing either a 20,000k LED strip or 445nm actinic blue. I just got a little freaked out because up until now I've only dealt with FW. But yeah, I literally just set it up a day ago lol. I did have the sand in a smaller jar for a few days and didnt see any growth then with an aerator running because the bowl that arrived initially came in shattered
