Description
Directions
- Adjust the pool water pH value between 7.3 and 7.8 and total alkalinity between 80 and 150 ppm as determined by a suitable test kit.
- Shock treat the pool water by adding 16 oz. of GLB Granular Chlorine per 10,000 gallons of pool water. Before using the pool, be certain the chlorine level returns to 3-5 ppm.
- Shock treat your pool at least twice monthly (weekly is recommended for most residential pools) according to step 3 above. During hot weather and peak swimmer loads, shock treat your pool weekly to prevent water cloudiness and algae growth.
NOTE: Follow label instructions for dosage to establish or raise the residual chlorine reading.
