    Should I raise my CYA?

    When I started testing my pool my CYA was under 20. I added about 2lbs. of CA and now it reads 20-25 maybe. I never get full sun and maybe get 3-4 hours of partial sun on my pool. I'm trying to keep my FC around 3 now and my CC is .5 or less. Would a higher CYA benefit me?

    If you added dry CYA, it takes about a week or so before it will register on the test completely. In WI, I would think 30 would be sufficient though.

    ^ +1 Especially since your pool gets no direct sun and only a couple hours of partial sun.

    You're done SLAMing when:
    1)You lose 1ppm or less FC overnight, & 2)You have .5ppm CC's or less, & 3)your water is clear.
