    TF-100 and Pool store test don't agree?!?

    I have been testing the water about a month now and was going into the Pool store to buy more conditioner to bring up the CYA and decided to take a sample for them to test. Now I don't know what to think?? They talked me out of buying more conditioner. Any thoughts? Thanks

    My results with TF-100:
    FC 3
    CC 0
    Ph 7.5
    CH 275
    TA 70
    CYA 25
    Salt 3500

    Their results:
    FC 3
    CC 0
    Ph 7.8
    CH 230
    TA 130 *
    CYA 60 *
    Salt 2900 *

    * denotes significant differences IMHO
    Note: 2 gallons of liquid Instant Water Conditioner have been added since plaster.

    From looking at other threads, I will answer my own question!!! lol

    One can believe the TF-100 or the pool store, only you can decide!!

    My impression is that if you have the same water tested by multiple pool owners with TF-100/K-2006 kits they will tend to get relatively similar results, but if you do the same with multiple pool stores you will typically see much less similarity. Given that, going with the TF-100 results seems like a good choice.

    This is obviously totally unfair to the occasional pool store that always has experienced people using accurate tests in a consistent manner, but those seem to be much more of an exception than you might initially think.

    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!
