How It Works FROG® Jump Start® provides a dichlor chlorine shock with a unique effervescence that is designed specifically for starting-up a freshly filled spa. It’s a one-dose-fits-all shock product that dissolves quickly. The bubbling action properly sets the initial chlorine level on spas up to 500 gallons and creates a start-up level of sanitizer that can be used to help find the right setting for the bromine cartridge (see manual for instructions).
