I recently had my pool renovated after 17 years. The coping, tile and plaster were replaced. I chose Quartzscape Barbados Blue as my finish. Day one as the water was being dumped I noticed spots and streaks in the new finish. Everything has been maintained properly. Brushed 2X per day for the first 14 days and once a day thereafter. We are on day 21. I had the plaster contractor come out and take a look at my concerns. His response was "scaling." I am having a hard time believing this as we did everything according to the NPC startup procedures. His suggestion was to start a treatment of stain and scale remover and that all would be well. I am just looking for thoughts as to what the real issue may be. The spots on the attached photos are actually indented on the swim out step.
