|Ask The Expert: How often to test
How often should I test the salt levels in my swimming pool?
The salt level should be tested monthly and any time there is a problem. Unlike other parameters, such as chlorine and pH, the salt level in your water remains fairly constant. Salt is generally only reduced when water is lost from the pool and fresh water with a lower salt level is added back in. For this reason, the salt levels change slowly in the water and it is not necessary to test as frequently.
However, any time you have a problem with the pool, you should check the salt level to verify your generator is operating properly. For example, an outbreak of algae may indicate that your system is not producing enough chlorine and your salt level may be insufficient.
Many salt generators are also equipped with monitors to indicate when there is a problem with the salt level. When the system indicates a low salt level, it is always a good idea to test the water to determine how much salt to add rather than adding salt until the system indicates an acceptable level.
