This is brown. When I brush it it poofs brown. I've vacuumed it and a lot of the dirt gets caught in the hair net but the next day it's back. This happened last year so I think it's dirt. Within 5 days of filling my new pool I had these spots. I get a lot of wind and surrounding trees. Is algae ever brown? Only green ?
