Shock Your Pool for Crystal Clear Water In 24 Hours

Boost Chlorine

Chlorine sanitizes your pool to remove bacteria and other hazardous contaminants to keep water clean. Use HTH® Ultimate Shock Treatment to restore chlorine levels that have been depleted by the sun, rain and heavy use.

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.

Keep Water Clear

The fast-dissolving formula found in HTH® shock treatments acts quickly to restore clarity to your water so you can be back in the swimming pool within 24 hours. Plus, the treatment won’t overstabilize your pool or fade your liners.


How to Use HTH® Shock Treatment

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® Ultimate 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 parts per million, your pool is ready to use again.
