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.
