Reading above 10PPM Clhorine.

[likwid]

I currently have the ColorQ plus 7 test kit and it only goes up to 10PPM in FC and TC... Does anybody know any test kits that go beyond the 10PPM range? it hard to maintain a shock level of 21 PPM when you have no idea what your current level is.

The pool calculator has been pretty good at getting me to where I want to be but after calculating to 21.. you cant stay there if you don't know how much it dropped after 1 day/night.

Look into pool school here and read up on the 2 test kits recommended. TF100 man myself. They read up to 50 ppm FC.

Why, yes, I do!

It's a FAS-DPD test. It can read up to 50. You can buy it alone, or included in a Taylor K-2006 or TF100 test kit.
