Hello Reefers! =)

Can anyone know what kind of algae? Or idk what it is! It's like a small plant growing out from live rock. I'm running 22g sumpless nano tank without a skimmer.
Tank details & parameters :
Salinity 1.026
Amm 0 Nitrite 0 Nitrate 0
phosphate 0
Cal 430
Ph 8.0
Kh 8
Mg 1400

That is green hair algae. You’ll see it referred to as “GHA” here on the forum.
How long has your tank been up and running?
