DIRECTIONS FOR USE:
1. Check total alkalinity using a testing kit. The ideal recommended alkalinity level is 80 to 120 ppm with chlorine used as sanitizer and 100 to 150 ppm with bromine.
2. To increase total alkalinity by 10 ppm, dissolve in a bucket of water 16 g per 1,000 L of pool water. Add to the pool water.
3. Check alkalinity levels regularly and make necessary adjustments.
