What is Saltwater Hot Tubbing all about? Making Chlorine out of Salt is a basic principle and should apply to most salt systems. In this article, I will give you all the details of the system I am most familiar with, the Watkins freshwater system, and how to use it properly.

As you read through, I will answer these essential questions about a Salt Water Hot Tubs

What is a Salt Water Hot Tub

Saltwater sanitation systems have been around for a while for swimming pools and are nothing new.  What is unique and different is that salt water has been adapted for specific use in their hot tubs. If you are unfamiliar with saltwater sanitation, it is taking sodium chloride or sodium bromide salts and converting them into either Chlorine or Bromide, depending on the system.

How do I get a Salt Systems?

Currently, only a few manufacturers of salt water sanitation. The one I know the best is from Watkins Manufacturing, sold under the Hotsprings and Caldera brand of hot tubs.  

There are other third-party manufacturers of salt systems on the market. I would use caution when considering a third-party salt system. Some hot tub manufacturers may reject a warranty claim if the salt system chemistry damages parts. If a part becomes corroded or damaged due to poor water chemistry,  the salt system may blamed, and the manufacturer will not cover the warranty claim.

Why is a salt water hot tub better

  • Automatic Chlorination. It makes its chlorine for a Year.
  • Conserve water by reducing spa drain and refills for up to a year
  • Softer skin. It is not as harsh as chlorine or bromine-treated hot tubs.
  • Like Epson Salts, a saltwater hot tub helps your joints feel better and are more flexible. 
  • Fewer chemicals are added, and no harsh odors.
  • More natural-feeling water with no itchy, dry skin or eyes.
  • Simple water care means more time enjoying your spa.

How to Use the System

In past years, I have attended Watkins Wellness Freshwater Salt seminars. The guide I have written is everything I learned, including best practices for their system. As a bonus, I have included some of my water care tips to enhance your overall experience with the system.

These water care instructions should apply to most saltwater systems as they work similarly. Of course, you should check the owner manual of any system and follow their guidelines for proper operation.
