Target for the 70 CYA is 5. For extra measure I'd aim for 6

I just tested yesterday, thought numbers were pretty good. Pool was spotless yesterday evening and I come out this morning to this. Is this algae? Can I get algae at 5ppm Chlorine? I'm not sure what I need to do. When I brush it, it comes off in a cloud. I added 1.5 lbs CYA yesterday evening to try and bring it up. I haven't retested yet.
