ACE Salt Water Method

IMPORTANT:

  • Always read & refer to the owner’s manual for complete information.
  • Test your water with a test strip once a week, or each time the spa is used. This step takes less than 1 minute!
  • The ACE system requires feedback/input; it is not a “set it & forget it” system.
  • Use the hot tub only when the chlorine level is between 1- 5 ppm. Boost or manually add chlorine as needed.
  • Low/No Use: For vacations, or if the spa is used once a week or less, decrease the Use Level to 1.
  • For extended vacations or periods of non-use, shock the spa water and set the Spa Size to 2 and the Use Level to 1. If you are unsure about your settings, contact your Hot Spring dealer for direction.
  • It is the spa owner’s responsibility to adjust the Use Level to prevent over or under chlorination.

Frequently Asked Questions

SHOULD I WEAR GOGGLES WHEN HANDLING CHEMICALS?

Wearing goggles is recommended when handling liquid chemicals. Gloves should be worn no matter the chemical type.

HOW DO I LOWER THE CHLORINE LEVELS IN MY SPA?

If you’ve added too much chlorine to your spa, the fastest method to bring your water back to the recommended ppm levels is to drain water from your spa, replacing it with fresh water from a hose.

WHAT DOES SHOCK DO?

Shocking your spa water means that you are oxidizing the sanitizing chemical, in this case Bromine. This can be accomplished using a chlorine or non-chlorine shocking agent. An advantage of non-chlorine shock is that it allows you to enter the spa much sooner than chlorine. The disadvantage of non-chlorine compounds is that they will not eliminate combined chlorine such as breakpoint chlorination.
