    Clompleted first SLAM. Things are looking good.

    Two days ago, after 3 days of SLAMming, the pool passed two of the three tests. CC was 0, overnight FC dropped half a point down to 19.5. But, the water was still a little cloudy. By evening the FC had dropped to 13. So I raised back to 20. Yesterday the pool started looking clear, so I let things coast. This morning the FC was 15.5 and the pool looked even more clear. This evening the FC had dropped to 9.5ppm, with sparkling water, as clear looking as when I filled the pool. Since FC had dropped below 10 I felt I could run the other tests:

    FC = 9.5
    CC =0
    PH = 7.6
    TA = 80
    CH = 160
    CYA = 50
    CSI = -0.1

    I am using bleach for chlorination.

    Those look like very nominal numbers to me. The pool math page suggest a goal FC of 4 to 8. Tomorrow evening I am planning to establish FC at 8, and then check it again the next evening. Does that sound right to y'all? I don't want to lose all the ground I have gained in the last few days.

    This is amazing, after so many years of struggling. I am in debt to this site and its many experts. The water looks great, and feels great. I could not be more pleased.

    Thank you all so much!

    Hey Steve. While you passed 2 of the 3 SLAM requirements, technically there was still one unsatisfied. So the true success of that SLAM is probably yet to be known. Still, you seem to be pleased with your effort so that's good. Other than perhaps your CH, yes, your numbers look quite good. As you mentioned, and I agree, I would continue to watch the FC level drop overnight, and perhaps watch your CC real close too. If there is anything (bad) remaining from the SLAM, you'll know quick, and you now know how to handle it. Happy to hear your water cleared for you. Let us know if you have any more questions.

    Thank you Steve. Once I realized the value of TFP and the money saved from taking advice from a pool store, I did the same. You should receive a profile "banner" update soon. Enjoy that clear water!

    Re: Clompleted first SLAM. Things are looking good.

    You've got the method right. Target, dose, retest. When you find the target goal that keeps the FC above minimum until you next test and dose, you're there.

    Realistically, all you need to do now is maintain adequate FC and keep pH in range, brush often, and vacuum, and it will stay sparkly all summer long. You'll want to test the lesser parameters occasionally, but that's not such a chore.

    You're now at serious risk of becoming a pool snob , refusing to enter any pool not up to your standards of clarity.

    Troublefree does not mean Maintenancefree. It's like brushing your teeth: You can spend a couple minutes a day and pennies a week or go to the dentist once a year and spend several thousand dollars.
    A pool is like a pet - you have to feed it every day, even the days you don't want to play with it!
