If cyanuric acid goes above 100 ppm: raise free chlorine to 2.0 ppm and test disinfectant, pH and CYA daily until it is back under 100.
Interactive water features follow Subchapter M (records kept 2 years).
State columns
Florida's DH 921 fields, Ohio's and New Jersey's every-few-hours layouts, Texas, California and the others: the sheet follows the state.
Limits printed
The legal minimum and maximum are printed on the sheet, so whoever tests knows on the spot when to act.
