Salt water systems use chemical reactions to generate chlorine from salt. Salt cell technology has commonly been utilized in large bodies of water such as pools, but more recently has made its way into portable hot tubs.

  • These systems use regular pool salt (sodium chloride), which some users feel offers softer water.
  • Water needs to be tested weekly and shocked with a granular oxidizer at start-up and at least monthly. Heavy hot tub use requires additional shock.
  • Sanitizer alternatives, such as bromine, are not available in salt water systems.
  • Salt speeds up the process of corrosion on spa equipment and nearby electronics. Hosing off the spa and deck after use can help prevent salt buildup from splashes.
  • Salt water chlorine generators can be sensitive and require close attention to detail, from carefully controlling calcium hardness to cleaning filters that prolong the life of the cell.
  • It’s easier to over-chlorinate a spa with a salt water chlorine generator because it has a dramatically smaller volume of water than a pool.

Salt water systems are a somewhat new trend, but UV-C technology remains an easy and consistent method of water care, especially when paired with an ozonator. As a premium spa manufacturer, Jacuzzi® Hot Tubs chooses to utilize CLEARRAY® UV-C technology and offer the option to add in a CLEARRAY® PRO3TECT automatic oxidizer, for a water management option that is practically effortless. In the next section, we’ll go into more detail about just how easy traditional water care is—and show you how clean your water will be.
