Helpful Tips
• This product may cause a falsely high total chlorine reading for up to 48 hours after treatment.
• Potassium peroxy-monosulphate has a low pH of approximately 2.3. Overdosing may lower both pH and total alkalinity, so test the water regularly.
• Allow adequate ventilation during oxidation, particularly for indoor spas.
