Is this biofilm?

I noticed these white cotton-like spots on the driftwood of my ecosphere after adding my snails to it. Is this a normal biofilm/ mold, or should I be worried? The aquarium isn't even sealed yet. Should I scrub it off or not? Thanks !!

My ecosystem setup:

It includes Hornwort and Moss from a pet store and the species of my snail is Tarebia granifera.
