Contrary to what many people think, there is no set standard for the production percentage. Several factors can affect the percentage required (outside temperature, water temperature, number of bathers, quantity of water in the pool, etc.). The first season with your salt system will require more analysis on your part in order to better understand its operation. It will be important to test your water regularly in the morning to find the right balance.
To help you understand how your salt system works, we can compare it to sanitizing with granular chlorine. This method also requires a daily adaptation according to surrounding factors. During heat waves or long periods of swimming, the number of granules needed to maintain the water chemistry will be much greater than when the pool is not in use or when temperatures are colder. The salt system method works in the same way, but without the handling of chemicals. Therefore, each day you will need to test and adjust the production percentage as needed to keep your chlorine level within the recommended parameters.
