Saltwater pool maintenance should include testing the water weekly for pH and free chlorine; monthly testing for salt, alkalinity, calcium and stabilizer; and opening and removing the cell every three months to clean any debris or deposits. Routinely clean debris from the filter, pump and skimmer.
Test strips and drop test kits are available for water testing, and the owner's manual of the pool should list the ideal levels for each type of test. To remove scale buildup from the cell, flush it with a high-pressure hose, or scrape it with a plastic or wooden tool. If these fail to remove the scales, a mild acid wash may be necessary. In the winter, remove the salt cell and flow switch for storage, replacing them with dummy cells until spring.
