Olympic Swimming Pools use about 650000 gallons of water, so if you're trying to shock one using 10% liquid chlorine, you would need about 200 gallons of liquid shock - or if you're only adding choline as a primary sanitizer, not as a shock, you'd use about 65 gallons.

How large is the pool? In ground or above ground? Shape? Above ground is easier to calculate. I have an oval above ground pool which is 18 x 38. It holds approx. 15,000 gallons. To get an accurate answer, you need to be far more specific.
It depends what concentration you need in the pool. If it's 0.1% - you need 4.5 gallons. For a 0.01% concentration, you need 0.45 gallons etc.
Since 1 gallon equals 90,840 drops and 1 Olympic sized swimming pool has 660,430 gallons, there are 59,993,461,200 drops in an Olympic size swimming pool.
FINA sets the standards for the size of Olympic pools. The volume of an Olympic-size swimming pool is 660,430 gallons or 88,287 cubic feet.
You have to add more chlorine.
Use one gallon of chlorine for every 10,000 gallons of water.
If you have a "chlorine generator" that requires salt in the water, ALWAYS refer to the manufacturers recommendations for the proper amount.
