    No pink color after adding R-870? All numbers 0? Problem?

    This is my first year since using BBB opening without it being a green swamp, so I've never opened with a mostly clear pool. I haven't started the mechanics of opening yet, but reached under the cover and took a water sample from arm's length depth.
    Test Results:
    FC 0
    CC 0
    TC 0
    pH 8.2
    T/A 110
    CH 350
    CYA 15
    Temp 65

    When I added the R-870, the water didn't turn pink. Is this good news? I ordered all new reagents from TFKtestkits this spring, so I don't think that's a problem. I've never opened without having to shock, is this the case?

    I had problems with scaling last year so I just added a quart of stain and scale preventive (Keetrol Plus, also added one quart at closing last year) and started circulation with a submersible pump. Should I add a floater with a tab in front of the input hose? I have some from vacation last year.

    Also, my first step is going to be to add acid, then go from there for CYA and further balancing.
    thanks, as always!

    Those zeroes mean no chlorine. No pink, no chlorine.

    With pump running, first lower pH to 7.4ish. Then add CYA and chlorine.

    After you add chlorine, you can then test FC/CC.

    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.
