The liquid pool shock I purchased is 10% sodium hypochlorite. Label on it reads: "Every seven days, or as necessary, superchlorinate the pool with 54 to 108 oz. of this product for each 10,000 gallons of water to yield 5 to 10 ppm available chlorine by weight.

My pool has 12,500 gallons of water. How many ounces should I use? Thanks.
