1. Test pH Levels
Dip an HTH® Multi-purpose 6-Way Test Strips (sold separately) into the water to measure total alkalinity, pH, free available chlorine (FAC), calcium hardness, and stabilizer or cyanuric acid (CYA). Balance water, and adjust alkalinity and pH levels, where applicable.
3. Wait & Test Chlorine Levels
If any granules settle along the bottom of the pool, use a brush to disperse until granules are dissolved. Once free available chlorine levels are between 1 and 4 parts per million, your pool is ready to use again
