Boost Chlorine

Kill Bacteria & Algae

Low chlorine levels, poor water circulation and warm weather can encourage bacteria and algae growth. Rid your pool of black algae, mustard algae and green algae and prevent regrowth by shocking your pool once a week. Don’t forget to brush the floor and walls of the pool.

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.
