    testing fc question

    I know I need to shock to 20 but I have a taylor 2000 kit ( I purchased wrong one by accident and then purchased additional reagents separately so I have everything now ) however, my comparator only shows numbers/color chart 0-5 on it how do I know if I have reached 20? Maybe im missing sorry but thanks so much, in advance.

    You need the FAS-DPD chlorine test to measure levels around 20. The reagents it uses include R-0870 & R-0871.

    If you have the FAS-DPD reagents, you need one of these. DPD powder is R-0870, and FAS is R-0871. Not a color comparison.

    If you purchased the R-0870 and R-0871 FAS-DPD reagents, you don't use the comparator. Use a vial.

    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!
