    cc calculation ?

    I am following the directions on my tf100 kit and it seems the most accurate reading I can get is down to .5. How are others testing to .2 or less? I see others with readings of .2 & .6, not sure how they get those. Thx

    Use 25 ml sample instead of 10 ml and each drop counts as .2. Everything else stays the same.

    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!

    Unless you have a commercial pool there is no point in testing by 0.2s. The additional precision is not useful and it uses up reagents more quickly.
