A 15-by-30-foot circular pool with a depth of 48 inches on average can store 12,000 gallons of water. A pool with identical outside dimensions and a depth of 52 inches on average contains 14,800 gallons of water.
To calculate the amount of chemicals to add to the water, it is required to know the size of the swimming pool. When utilising liquid chlorine, 11 ounces per 10,000 gallons of water should be added daily. To shock an out-of-balance pool, up to 104 ounces of liquid chlorine per 10,000 gallons is required. The same amount is required for pool cleaning following winter.
