My water looks very clear, and my numbers seem fine, but I noticed 2 small spots of algae (green color) on the wall in the deep end of my pool. They were both about the size of a frisbee and I could easily brush them off. Right now I'm losing about 1 ppm of chlorine at night and about 2-3 during the day. CC hovers between 0 and .5. I've got a lot of kids in the pool, which I'm sure is contributing to the higher chlorine usage during the day. Also a lot of direct sun. From what I've read on this site, I should not need to shock the pool, but yet this algae has popped up. If I do shock it, should I just take the chlorine level up to 20 overnight?
