    TFP Test REsults - How to adjust water chemistry?

    I opened my pool recently and tested with TFP kit and got the following numbers:

    pH 7.4
    Cl 0
    Br 0
    FC 1.5
    CC 0
    TC 1.5
    T/A 50
    CYA 20

    I need help in adjusting as I am having trouble following the pool calculator. Help would be appreciated.

    sand filter
    vinyl liner
    in-line chlorinator

    Hi Tony,

    First, ignore the Br side of the scale as that is for bromine pools. You read the Cl and pH on that kit.

    It does appear that you have a little color challenge reading the OTO kit with seeing that as 0 FC and the FAS/DPD as 1.5FC. Lots of folks have issues with the yellow colors deciding which # it actually is! Often, we break out the FAS/DPD and use that.

    Your pH and TA are fine. CYA and FC a little low.

    What help do you need w/the calculator?

    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.
