How much chlorine should I use in my pool?

These charts will give you an estimate of how much chlorine to buy and use. Our suggestions for a season’s supply are based on past experience in a 4 month season, with average weather. If you live in a warm weather climate or keep your pool open much longer, please base your seasonal use on these factors. Your actual use will depend on such variables as: type of filter, local weather, bather load, closeness to trees and plants, careful water testing etc. Always read directions carefully and use all chemicals as directed on the label.

* The amount of chlorine you will need to add to your pool water is affected by many factors. These include high water temperatures, heavy pool usage, and heavy rainfall and pH levels of the pool water. It is important to measure your free available chlorine level often and adjust your dispenser as needed to increase or decrease the flow.

** Read labels and follow instructions carefully before adding any chlorine to your chlorinator or floating dispensers.
