    Test Sample

    Hello All,
    I usually take a sample to the pool store (out of curiosity) once every couple of weeks, but if I took a sample in the morning and left it in my car for 9 hours would it affect the results?
    I pass the pool store on my way home from work and would save me a trip back.
    I do have a TF-100 kit and everything has been fine using the BBB method ( thanks everyone) and usually get a sticker on my printed test results for having a well balanced pool.

    Leaving a water sample in your car that long will certainly affect the FC level and PH (unless FC is zero to begin with). It should not affect the TA, CH, or CYA levels significantly.
