    More Calcium hardness

    Please do not hijack the thread. Start your question in a new thread....

    Hi folks,

    Purchased the TF-100 test kit last year.... Opened my pool last Sunday (6-2-13).
    Shocked the pool and ran filter for 24 hours. My wife brought a water sample to Leslie yesterday....

    Here are the results.... (new guy at the testing station without a clue)

    FAC 3
    TAC 3
    CH 500+++++
    CYA 40
    TA 120
    PH 7.4
    Copper 0
    Iron 0
    PHO 300


    When I got home about 6 hours later I tested the calcium hardness myself and got 300....

    QUESTION:
    The kit instructions say "add R-0012, one drop at a time, til color changes to blue"
    I did this and at drop 30 it changed to a purpley blue..... Is that when to stop or do I need to keep adding R-0012 until it turns to a blue..... I always thought it was a signifigant color change....

    Also at Leslie they stoped the test and told my wife it above 500

    any help would be greatly appreciated....... Thanks again

    Using the TF-100, I would trust your test results over the pool store's.

    Continue adding drops as long as the color continues changing. The final drop that does not cause any further color change doesn't count. For example, say you added 32 drops and the 32nd drop did not change the color, subtract that last drop which results in a total drop count of 31.

    Here are more complete instructions on performing this (and other) tests.

    A good test kit is an investment, not an expense.

    Blue means sky blue. Almost the color of the little box the pH tester is in.
    16K freeform gunite with spa; Pentair 4000 DE filter; Century Whisperflow 1 HP; Pentair Minimax heater.
    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!
