If you're lucky, then your pool is rectangular and equally deep everywhere. In that case, take a long ruler and measure the length and the width. Stick the ruler in the water until it touches the bottom, and use that to measure the depth. Multiply the three numbers together and you'll get the volume. Unfortunately, you'll get the number in cubic feet or cubic meters, and you probably want it in liters or gallons. How to convert: Cubic meters to liters: multiply by 1000. Cubic meters to gallons: multiply by 264. Cubic feet to liters: multiply by 28. Cubic feet to gallons: multiply by 7.5. If you're not so lucky, your pool is deeper in some places than in others. Hopefully, the bottom is at least flat: if it is, then measure the depth at two opposite corners and average - do everything else as in the other case.
Call your local water company.

You get a salt water chlorinator installed and add the correct amount of salt to the pool advice is available on this from your local pool shop.
A pool that is 16'x32'x5' would hold 19,200 gallons of water. You can use a pool volume calculator to help you figure the actual volume of water your pool will hold.
The average swimming pool takes 18000-20000 gallons of water to fill
how deep you are in the water.
simply buy the required amount of salt for the pool from a pool shop or other salt supplier and and toss it in the water.
W(15) is the number of gallons of water in the pool after 15 minutes.
