    Lightbulb Compared two stores' test results of the same water.

    (Just to anticipate worries about the water in the AGP and otherwise - this post's purpose is not about advice about what to do, it is just a comparison).
    Today I did an experiment.

    I took two samples, one of my IGP water and the other from the AGP, and went to two different stores (one being Leslie, another one is a store I go to usually) and asked them to test the two waters.
    The Store#2 BTW is the one that did initial test on my IGP and confirmed high CYA I suspected, so for me these number are more important because they show dynamics using the same test kits.
    Leslie (Store #1) obviously uses dropper kit and strips, and the Store#2 uses computerized tests.
    The test was not a mere curiosity, I needed to test my CYA as I am trying to lower it. It was initially tested at 91ppm.

    Anyway,

    Here are the results. (NT means "Not Tested")

    IGP

    TEST Store #1 Store #2

    FAC 7.5 6.79
    TAC 7.5 6.79
    pH 7.6 8
    TA 110 92
    CYA 60 77
    CH 210 182
    TDS 100 N/T
    Phos 200 ppb 400 ppb (see Note 1)

    Note 1- from the previous test 2 weeks ago, nothing has been done about it so I take it it'd be the same.


    AGP

    TEST Store #1 Store #2


    FAC 1 0.2
    TAC 1 0.41
    CC 0 0.21 (calculated)
    pH 7.2 6.5
    CYA 10 16
    CH 90 34
    TDS 300 N/T
    Phos 100 ppb N/T


    Well.....while some are close, some are different.
    And when it comes to pH, for one pool the difference is positive while for the other it is negative. One would think it'd be consistent?

    Food for thought.
