Non-Chlorine Shock Treatment
Oxidizes and rids spa water of non-filterable contaminants, which then allows regular disinfectants to work better.
Active ingredient: Potassium Peroxymonosulfate
Directions for use:
Initial Dosage - 1 1/2 oz ( 1 1/2 capfuls ) per 500 gallons to ensure thorough oxidation.
Further treatments depend on bathing load, but at a typical rate of 3/4 oz. ( 1/2 capfuls ) per 500 gallons.
Entire required dose should be added at one time; broadcast product over water with jets running but not while hot tub is in use.
