What algae is this? I can suction the sand it’ll be back within two hours?

Could be diatoms. Is your tank new? If so, diatoms are normal and go away on their own. How are the nutrients in your tank?

I'd just put a few snails in there . .

It’s almost 3 months old, have snails two hermits, two emeralds and a tiger pistol shrimp. I guess it is considered new still.

3 months is still well within the time frame for succession and maturation from one algae type to others on the surfaces.
Also this...
" I can suction the sand it’ll be back within two hours?"
Understand that this is far faster than the cell division rate for any algae. So if you suctioned the sand and it was white, then reverted to that tan/brown - then you are seeing settlement and movement of cells onto the fresh new surface.
It may feel pointless, but I guarantee manual removal of brown accumulations outruns algae division rates - you just have to do it a few times.

Then I’d say it’s diatoms and the “ugly phase” of a new tank. I’d just let it be and keep your parameters in check. It will go away on its own. No way to avoid this stage in a tank’s development. Good luck!
