    r-0871 REFILL test problem

    ordered refill's for dpd fas kit and wife used the 2 oz. bottle to do test and came out with FC- 23.5 and CC-2
    so i retested using the .75OZ bottle that came with kit 6 hours later and had FC-19.5 CC-1
    should i continue using .75 oz bottle? thats what i started with.

    With that CC level to start, and the retest 6 hours later, I'm not sure there's a discrepancy. The only way to know for sure is to run two tests back-to-back (or side by side) and see if they are within a drop of each other.

    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!

    You also want to be sure to get the water level in the tube as close to the same exact level each time. Just being a little bit off can make a measurable difference.
