Are small amounts of algae normal? I have a few small streaks and patches of algae on my pool walls and safety ledge daily. I brush them off daily and it takes about 10 mins to do all. Water is sparkling.
I had an algae problem a month or so ago. Shocked for over 2 1/2 weeks with several days (twice) at mustard algae levels. I'm passing the overnight test but can't get the CC to 0. My cc is always .5 to 1 even after shocking. Info here:
