DIRECTIONS FOR USE:

2. If water is extremely hard, double the dosage to 120 mL.
3. Once the spa is full wait 1 hour before adding the sanitizer. Adding the sanitizer before the product has been fully dispersed may color the water.
4. Ensure that the sanitizer level remains between 3 to 5 ppm during treatment.
5. Rinse the spa cartridge(s) regularly during the first week.
6. Once a week, for maintenance purposes, add 15 mL per 1,000 L of spa water.
