NOTE: Wait for water to reach 21oC before beginning the treatment. The shock treatment neutralizes the enzymes. Allow chemical levels to return to normal before adding SPA ZYME, i.e. 1 to 3 ppm of free chlorine. Use clean and well-balanced water.
1. Normal Spa usage: add 75 mL of SPA ZYME per 1,000 L of pool water once a week, adding the product into the skimmer.
2. Heavy Spa usage: add 150 mL of SPA ZYME per 1,000 L of pool water once a week adding the product into the skimmer.
This product is safe and may be added even while the pool is in use.
