Thanks Watermom, I just ordered my test kit the K-2006 and filled out the pool form, kind of important to know the parameters. I have been using test strips but will post numbers once I get my kit and read the instructions. Kids are begging to get in the pool, the water is crystal clear but until I feel good about the chemistry I won't let them in.

I have a 20,000 gallon vinyl lined pool measures 32x16 ft, filter is a 300 pound Hayward sand filter with 3/4 HP Hayward pump, using 3" tabs in a skimmer.
