Salt

Ask a question hereIn the conclusion of our conversation with Lee Moore and Blake, Technical Director at AIS Water, we examine what it takes to make saltwater chlorination work reliably in demanding commercial environments.Commercial pools cannot be managed by reacting to every change with another drum of chemicals. Like steering a cruise ship, water chemistry requires calculated adjustments, accurate information, and equipment sized for the facility’s actual operating conditions.The conversation covers the difference between ORP and direct free-available-chlorine measurement, on/off versus proportional chlorinator control, and how properly sized systems respond to sudden increases in bather load. Lee and Blake also explain why some facilities retain liquid or granular chlorine as backup sanitation—even when onsite chlorine generation handles nearly the entire demand.We also challenge some persistent assumptions about saltwater pools. Modern commercial systems can operate at salt concentrations as low as approximately 950 ppm, opening the door for indoor pools, facilities with natural stone, and other applications where corrosion concerns have discouraged saltwater chlorination.Finally, we look behind the marketing of “mineral pools.” Magnesium and potassium salts may change how the water feels, but the sanitation still comes from chlorine produced through electrolysis. Minerals do not replace the sanitizer.Topics discussed include: Why commercial chlorination begins with accurate system sizing  Accounting for sunlight, bather load, turnover, and unusual applications  Why water stability is more important than constant chemical correction  Direct free-chlorine probes versus traditional ORP control  On/off and proportional 4–20 mA chlorinator control  Responding automatically to sudden increases in bather load  Cell operation, reversing cycles, and expected service life  Using liquid or granular chlorine as secondary sanitation  Reducing chemical handling without removing backup infrastructure  Liquid chlorine degradation, declining strength, and chlorate concerns  Commercial chlorination at approximately 950 ppm salt  Saltwater systems for indoor pools and natural-stone environments  What “mineral pool” marketing gets right—and what it leaves out  The roles of magnesium and potassium in swimmer comfort and water appearance  Why mineral pools are still chlorine pools If you operate, specify, design, or service commercial aquatic facilities, this episode offers a practical look at building a chlorination system around stability, predictable demand, and intelligent control—not chemical firefighting.
