Freshwater pH/Alkalinity Down

Why is pH and Alkalinity Important?

Hot tub water pH is the most important component of water balance next to the sanitizer. It determines how acidic or basic your water is. When the pH goes out of the proper range it can cause a lot of problems and even damage your spa. Unbalanced pH can cause your sanitizer (Chlorine, Bromine, biguanide) to not work properly, corrosion, scale formation and more. pH should be maintained between 7.2 and 7.8.

When do I use Freshwater pH/Alkalinity Down?

If your pH or Alkalinity are high use Freshwater pH/Alkalinity Down to lower them.  This dealership strength product lowers spa water pH levels. This product should be used with the Freshwater Water Care System, Freshwater Salt System, and Hot Spring ACE Salt System.
