    Testing cya

    I was testing for the first time and I'm assuming if the samPle itself of 7ml doesn't turn cloudy at all at the 14 ml point the cya level is extremely low. When I filled the glass the black dot disappeared suddenly but I think it was because of a top water reflection that made the dot verysuddenly disappear

    Sound correct?

    That doesn't sound right. Did you mix half pool water and half R-0013?
    Did you swirl according to the directions?
    Did you slowly pour it into the view tube until you couldn't see the black dot anymore?

    Also, here's a link to Extended Test Kit Directions for each test. The CYA directions have a link to Taylor Technologies that has pics of the CYA test process:

    Once the dot disappeared I stopped filling and the gauge was about 30 but once I stopped filling the dot came back. The sample was 7 ml water and 7 ml cya agent and stirred yes.

    I have a 4600 gal pool 14' 48" intex, and have added approximately 10.5 oz of the biclorinate granules with the stabilzaer into a utility water fresh fill.

    Well then the sample is below the detectable level it seems.

    Re: Testing cya

    I do my CYA test, normally in the A.M. with the sun at my back. I hold the vial 'navel' height just away from my body, so I can see straight down into the vial. I squirt a good amount of the mixture into the vial and swirl it to eliminate any bubbles. If dot is visible, I dispense a series of short squirts until the dot is gone.

    After testing, I dump the contents from the vial, rinse the vial in pool water, briefly shake the sample bottle and perform the test again.

    Re: Testing cya

    This is my first chance to look at some numbers. It appears from pool calculator that my CYA test is probably valid.

    If I had ~4500 gallons of fresh water from the utilities and placed in 10 oz over a few days of diclor which I understand to be about 60% Cl and 40% Stabilizer? pool calculator is calling for 19 oz by volume of stabilizer to go from 0 to 30 so if I put 10 oz of diclor in only about 4 oz of stabilizer is in so far putting the CYA under detectable levels.

    Can someone confirm this is about right?
