Application & Water Care Guidance

1. Read the container first: Follow the full product-label directions for dosing, application, and safety. The amount needed depends on your spa's water volume and test results.
2. Maintain the directed chlorine residual: The supplied product information specifies 1–3 ppm chlorine. Follow the current container label and your spa manufacturer's recommendations for your setup.
3. Keep pH balanced: The supplied directions specify a pH range of 7.2–7.6. Test regularly and adjust according to the product label.
4. Shock only as directed: Follow the container's specific shock-treatment instructions and bathing re-entry requirements.
