Salt Systems are designed to maintain an already pre-existing 3 - 4 ppm (part per million) of free available chlorine. Salt is added to the water in the pool making a saline solution. The saline solution then goes through an electrolysis process that converts the sodium chloride molecules in the water into sodium and chloride. The chloride molecule produces the sanitizing power of chlorine which is hypochlorous acid. Once the chloride molecule has sanitized its portion of the water, it links back up with the sodium molecule creating sodium chloride again. This process is repeated over and over again to maintain proper chlorine levels sanitizing the water.
The cell has a small amount of built-in maintenance capability by reversing the polarity of the cell. This feature alone is not enough to keep the salt cell completely clean, however. It is suggested to manually clean the cell at least every 3 - 4 months. To manually clean a salt cell, it should periodically be soaked in a muriatic acid and water solution mixed with a 1:4 ratio. This solution can be placed in a bucket for the cell to soak in. Although most manufacturers suggest using a salt cell cleaning stand. The salt cell cleaning stand threads onto the bottom of the cell. This allows you to use less acid and water-saving you time, money and chemical resources.
Typically cells will last anywhere from 4 - 6 years depending on the cleaning schedule and percentage of generation being used. All salt cells are designed to sufficiently produce enough chlorine up to a specified amount of gallons. Salt cell sizes usually are designated with a range between 11,000 to 60,000 gallons. If you have a 15,000-gallon pool it is suggested to get the 40,000-gallon cell. The reason for this is because the cell will run at a lower chlorine generation percentage. This reduces the wear and tear of the cell making it last much longer.
Most Salt systems also come with a flow switch to prevent generation in low flow situations. This prevents gas build up in the plumbing and potential damage to the system. Salt systems have a feature to read the amount of salt that is in the water. This lets you know if the salt level is in the proper range. Salt chlorination systems have an ideal salt ppm range. It’s important to check the owners manual for your specific salt systems ppm range to ensure optimal generation of chlorine.
Swimming in salt chlorinated water feels much softer on the skin, hair, and eyes. This is due to saltwater having a naturally basic pH and the salt system generating a pure chlorine ion sanitizing the water. Tablets contain fillers and other byproducts that can irritate the skin. The pH of saltwater is closer to that of human tears, neutral on the pH scale. This will require the use of more pH balancing products like muriatic acid and granular pH down. Salt chlorinated pools are more corrosive than traditionally chlorinated pools. It’s recommended to install an in-line anti-electrolysis sacrificial zinc anode to help reduce the corrosion effects from the water.
