is this hair algae?

[BGK21]

Hi all,
I am midway through setting up my first tank. I am half way through a fishless cycle and noticed what appears to be a spider web....would this be hair algae? If so, how could i get rid of it? I am also noticing what appears to be dust in the tank. Is this normal?
Thanks in advance.

Is the driftwood new? That cottony white growth tends to show up on new driftwood; it'll go away eventually; you can wipe it off if it bothers you but it'll probably grow back for a bit. It's harmles. What color is the dust? White? Brown?

It is new. I soaked it for a week and then stuck it in. Good to know, i won't worry about it. The dust particles are tiny, could just be some of the new plants. Thanks!
