    Reading Numbers

    I've seen people posting the certain numbers FC, PH....Does your kit show exact numbers or you estimate? I have Poolmaster 22260 Basic 5-Way Test Kit. On chlorine tube, numbers are 5, 3, 2, 1, 0.6. Does your kit says 4.6, 0.8 or 2.5.......you estimated?

    Re: Reading Numbers

    The only really estimated numbers are pH and CYA. All others (FC, CC, TA, CH) you count drops until a color changes, so they are in even increments, usually 0.5ppm for FC and CC, and 10ppm or 25ppm for TA and CH.

    The pH still requires matching colors ... and the CYA you have to determine when a dot disappears.

    You are using a DPD or OTO chlorine test ... we recommend the FAS-DPD chlorine test due to its accuracy.

    Re: Reading Numbers

    I am pretty new with the pool stuff. This is the kit I got. To test Chlorine, I drop 5 drops in tube first and look for the color to match which numbers, not dropping one by one to see color change.

    Re: Reading Numbers

    That is the OTO test ... not very good at getting exact FC or CC numbers.

    See link in my signature for the kits we recommend.

    We get the FC level accurate to either .5 or .2 depending on the sample size, using the FAS-DPD test..

    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!
