Non-chlorine shock, such as Swim Worlds Oxidizing Shock “Shock 2” is an oxidizer. It uses the power of “active oxygen” to destroy contaminants in pool and spa water. This eases the load of your regular FAC residual, allowing that chlorine to stay effective longer. This, in turn, prevents chloramines from building up.
Oxidizing shock contains no chlorine. 1 lb. per 8,000 gallons of water.
