DIRECTIONS FOR USE:
1. Maintain proper daily levels; these levels are determined using a test kit.
Free available chlorine: 1.0 – 3.0 ppm
pH: 7.2 – 7.8
Total alkalinity: 80 – 120 ppm
Calcium hardness: 200 – 300 ppm
2. Protect residual chlorine from being destroyed by the sun's rays by adding one 200 g tablet per 10,000 L of pool water to reach 20 ppm. Add slowly in the skimmer.
3. To adjust the stabilizer level, keep in mind that each tablet per 10,000 L of pool water will increase the stabilizer level by 20 ppm.
