To be on the safe side you really need a test kit, and before doing the chlorine you need to check the pH level as this will control your chlorine. The pH needs to be between 7.4 - 7.6 if it goes above 7.8 then the chlorine does not work very well.
chlorine needs to be higher than 1ppm but below 5ppm the desired amount will be dependent on your plans for the pool and how it is used eg dirty kids in - out in the mud back in again this will eat up chlorine, deodourants hair products cosmetics sweat etc etc anything that gets in the water will eat it up.
But when it comes to how much chlorine to put in it is easier to add a bit more than try and get it out (without buying more products eg. sodium thiosulphate).
It will eventually become like adding sugar to a cup of coffee you get to know how much you need.
Pool brush and occasional chlorine or water changes so it doesn't grow in the first place
1-4ppm
High concentrations of chlorine can and will destroy a vinyl liner.
used it for years, no worries. The corroding metal pool fittings are what you need worry about
Need to rephrase question.
It depends on how big the pool is. From :)
This depends on the size of the pool. Generally, when you buy chlorine, it should say on the bag or box how much to use for what size pool.

That depends on what size pool you have. If you have a smaller pool, the amount would be less, and if you have a larger pool, the amount is more. Consult the instructions on a chlorine box for what size pool and how much to use.
one pound of cal hypo, granule chlorine, will treat 10,000 gallons of pool water. So use 1/4 pound to shock, two or three times that if pool goes green. If pool has a vinyl liner use sodium hypochloride, liquid shock, instead of granules.
If it is a vinyl liner pool you have to use a submersible pump. You can get a small one for right at $100.
Use a chlorine reducing agent. You can get them at the pool supply. One is called After Shock, but there are others.
