Where do you add the pH increaser and chlorine tablets in a vinyl pool?

You can add the increaser directly pool. The chlorine can be added in a couple different ways. Tablets can be used in a floating container or put in the skimmer basket. (I prefer the floating container. Granular chlorine can be added directly in the pool. Always make sure your pH is correct before you add any chlorine or you'll be wasting your money.

It's a good idea to take a sample of your water to local pool store dffor testing. It really helps me out.
