1. Test pH Levels
Dip an HTH® Multi-purpose 6-Way Test Strip (sold separately) into the water to measure total alkalinity, pH, free available chlorine (FAC), calcium hardness, and cyanuric acid (CYA) or stabilizer. Balance water, and adjust alkalinity and pH levels, where applicable.
2. Apply Directly to Water
Before handling any chemicals, put on protective gloves and goggles. During evening hours and with the pump running, broadcast the HTH® Super Shock! Treatment evenly over a wide area in the deepest part of your pool.
3. Wait & Test Chlorine Levels
If 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 ppm, your pool is ready to use again.
