Salt System Maintenance

In Blog by David Jerkins

A chlorine generator, also known as a saltwater chlorine generator, or just “salt system”, is a piece of pool equipment that uses salt and electricity to produce chlorine for pool sanitation. Chlorine generators are becoming increasingly popular in commercial swimming pools because they offer a more natural and low-maintenance way of sanitizing the water. In addition, they are typically more cost effective than more traditional means of sanitation, saving money over a period of years.

Properly cared for, some salt systems can last more than 10 years. It’s key to maintain the system properly to ensure a long lifespan of the equipment. To maximize the lifespan of your chlorine generator, it’s important to follow these tips:

  • Monitor salt levels: Chlorine generators require a certain level of salt to function properly. Make sure to monitor the salt levels regularly and add salt as needed to keep it within the recommended range. Refer to manufacturer’s guidelines for ranges.
  • Clean the cell: The cell is the part of the chlorine generator that produces chlorine. Over time, scaling can build up on the cell and reduce its effectiveness. Cleaning the cell regularly with a solution of muriatic acid and water can help prevent this buildup and extend the lifespan of the cell. Refer to manufacturer’s guidelines for instructions.
  • Keep the pH balanced: Proper pH balance is important for the chlorine generator to work effectively. Make sure to monitor the pH levels regularly and adjust them as needed to keep them within the recommended range. pH is paramount to water quality and should always be considered.
  • Balance the pool: Balance to LSI for best results. Keeping the water balanced will not only prolong the life of the salt system, but of all the equipment in contact with the water. Refer to your CPO manual for more information, or here: How to use LSI for my pool? – TMI Sustainable Aquatics (
  • Use pool salt: Use pure salt. No additives. The bag should say 99% sodium chloride and nothing else. Adding other salts can damage the equipment.
  • Perform regular maintenance:  Including inspecting and cleaning the cell, checking the salt levels, ensuring proper pH balance, and good LSI can help prevent problems and extend the lifespan of the equipment. Inspect the power supply for the cell as well: If the unit is air cooled, dust and debris could fly into the enclosure. Make sure there is no dust inside it. If there is, shut the unit off and remove the dust.

By following these tips, you can help maximize the lifespan of your chlorine generator and ensure that your pool stays clean and safe for years to come.
