The amount of chlorine required per gallon of water depends on the type of chlorine used to treat the pool. A daily dosage of 11 ounces of liquid chlorine is recommended for every 10,000 gallons of water.
A 10,000 gallon pool requires 6 to 8 ounces of granular chlorinator each day. The same pool needs two 3-inch, 8-ounce jumbo tablets each week. A pool usually needs a larger dose of chlorine if it receives heavy usage or a significant amount of rain. To shock a pool that is chemically unbalanced, up to 104 ounces of liquid chlorine is recommended for every 10,000 gallons.
