I have a brand new pool build and plaster that filled last Sunday. I started noticing spots within 3 days, i had been brushing twice a day. The PB added sequestreant and got levels started 24 hours after fill. I think the stains are growing so i assume it’s algae? What should I do since I can’t shock it yet. Pool builder is just forwarding my pictures to plaster company asking for advice. Pics below. Thanks!
