    Slamming question.

    I've had some problems with some small black spots in my pool. If I scrub them off with a wire brush there's still a faint spot there and if the Chlorine ever gets low they just come back. So my plan is to scrub everything real good and start SLAMMING. But we've had a ton of rain so my CYA is a little low. Should I bring that up to 70 first and then SLAM? Also my salt is almost at the point where I need to add another bag. But I'm thinking of holding off on that since I'm getting ready to add so much Liquid Chlorine. Here are my test results.

    FC - 2.5
    PH 7.8
    TA - 80
    CH - 240
    CYA - 50

    Leave your CYA alone when you start the SLAM.

    Add salt when the SLAM is complete.

    You should adjust your pH if you intend to SLAM.
