How do I control this algae?

[ASIN28]

Hey all,
My 120G tank has been running for about 2 months now, I cannot control this algae on my sand bed. I lightly vaccum it up and next day it’s all over again.
Salinity- 36
Ammonia- 0
Nitrite-0
Nitrate-10
Phosphate- .1
Ph- 8.3
Alk- 9.9
What type of algae is this, is this due to my system being fairly new?
Right now I have a dozen nassarius snails and trochus in the tank, will add some sand sifting gobies soon. But I also feel like vacuuming it does nothing but cover it.
Thanks

Would just ride it out looks like the ugly/diatom stage almost everyone goes threw this.

Best thing to do is nothing at all, it will go soon

Your tank is still pretty new, I would say it's just the ugly stage and diatoms. You just have to wait and they will disappear in their own time.
