Thanks, Watermom and Sherra.

Do you (or anyone else) know where I can find a testing kit that measures Chlorine up to 15 ppm? My "dropper" kit only tests up to 5 ppm. When I did measure the water again, it was off the charts and looked bright orange!

Also, at what level do you keep pool(s) for swimming? When is it safe for the kiddies to swim?

Thanks,

Paul
