Can someone help me identify this algae, and is it good or bad.

[Reefer newbie]

Hi I have a 120 gallon tank and it’s been up for 1 1/2 years. I just had my tank water sent for a triton icp test. Everything came back normal except for slightly elevated barium, and iodine. I just did a 15 % water change, and this is my parameters.
temp- 78*
ph-7.9
Pho’s-.06
Nitrate- .05
Salinity- 1.026
Can someone tell me what this algae is?

Also this wasn’t like this yesterday, I had a little on the rock that looks a little brown, and none on back window, and very little on overflow. It bloomed in 24 hours

Does it blow off easy? Kind of looks like cyano
