This algae is a common form of diatom algae - very common in new aquariums with new bio filter media / carbon etc (almost always a certainty to occur).

If left too long alone, it will become a growth bed for green algae and become significantly more difficult to remove.

The solution is to manually remove as much as you can during a water change, and add as many Amano shrimp as you can (15 are recommended for a 20 gallon tank). The algae should clear within 24-48 hours.
