    Black spot algae?

    Thanks for the input, I may run out tomorrow and get a new stiff brush. My older blended brush just barely gets these things and the robot cruises right over them. And I'll shock it up above 20 this time, instead of the usual 15 or so. Jim

    Question about shocking

    I'm currently trying to rid my pool of a small algae issue and have a question about "shocking". My CYA is ~70-75 so according to the Pool Calculator my shock level is 20-21. When I bring the FC level up to 21 and it then drifts down into the 12-17 range during the day/night, am I still...
