The easy-to-use treatment quickly eliminates unwanted bacteria and algae in your swimming pool, so your family can get back to swimming and relaxing as soon as possible. With this simple shock treatment, you can boost the chlorine levels in your pool and restore crystal clarity to the water. Plus, these shock pods are sun protected for extended chlorine life and also compatible with salt systems. TO USE: Always be sure the pump is running when testing the water or adding chemicals.  Test and adjust the pH to the ideal range of 7.2 to 7.8.  Add the recommended dosage directly to the pool during evening hours while the pump is running.

Boost Chlorine

Chlorine sanitizes your pool to remove bacteria and other hazardous contaminants. Use HTH® Pre-measured Water Soluble Shock! Pods 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. Shocking your pool once a week to boost chlorine levels will control the growth of algae, kill bacteria and destroy organic contaminants.
