GLB 71428A Super Charge 68% Cal Hypo Shock, 1 lb.

Item Number: AA7142805

GLB Super Charge Chlorine Shock is 68% active calcium hypochlorite (65% available chlorine) granular formulated especially for super chlorination swimming pool shock treatments.


  • Fast-dissolving, granular shock treatment
  • Destroys organic waste
  • Controls algae
  • Kills bacteria



  1. Use 1 lb. for every 10,000 gallons. Add total required amount at one time. Scatter product directly over pool water surface. Use SUPER CHARGE only when pool is not in use, as it will produce a temporary high chlorine level. Do not enter pool until the chlorine residual has dropped to a level of 2 ppm.
  2. Between applications, maintain required 1.0-3.0 ppm chlorine residual in pool water.


Always mix with only pool water by scattering product over pool surface. If you don't want to close the pool while shock treating, use a non-chlorine shock such as GLB Oxy-Brite.

Compatible with chlorine, salt water pools.
