What it does:

HTH Super Shock is a calcium hypochlorite shock (with 56% available chlorine) used for effective super chlorination. This shock treatment comes in a fast dissolving granular form. It destroys organic waste, controls algae, and kills bacteria. These contaminants can clog the filter, cause scum lines, and affect swimmer comfort. Super Charge can be used with chlorine and salt water pools.

How much you need:

1 lb per 10,000 gallons of water.

How to add it:
  1. Use Super Shock at the rate of 1 pound per 10,000 gallons of pool water. Add total required amount at one time. Scatter this granular product directly over the pool water surface. Use Super Shock only when pool is not in use. It will produce a temporary high chlorine level. Do not enter pool until the chlorine residual has dropped to a level of 2 ppm as determined by a suitable test kit.
  2. Between Super Shock applications, maintain required 1 – 1.5 ppm chlorine residual in pool water.
