A salt water hot tub is gentler on the skin, helping to alleviate irritation and can benefit those with conditions like eczema. It also reduces the use of harsh chemicals, which enhances air quality and environmental health. Despite higher upfront costs, the longevity of salt cells and decreased chemical use make it a cost-effective option over time.

If you're thinking about converting your hot tub to a salt water system, here are some of the key advantages you'll enjoy:

  • The water is gentler on your skin.
  • You will need to use less chemicals.
  • You will save money in the long run.

Gentler on Skin

Saltwater hot tubs are known for being much kinder to your skin. The water feels softer, which means your skin doesn't dry out or get irritated as it might with traditional chlorine pools.

People with skin conditions like eczema or psoriasis often find relief after soaking in saltwater.

Reduced Chemical Use

Your converted hot tub will use a saltwater generator to naturally produce chlorine. This means you'll use fewer harsh chemicals, which can lead to better air quality around your tub. It's a healthier option for both the environment and your well-being.

Long-Term Cost Savings

While upfront costs can be higher, over time, a saltwater system can save you money. You'll buy less chlorine and other chemicals, which helps reduce your ongoing expenses. Plus, a salt cell typically last for several years, making them a cost-effective choice in the long run.

What Are The Components of a Conversion Kit?

What Are The Components of a Conversion Kit?

A hot tub saltwater conversion kit typically includes the following components:

  • Salt Chlorine Generator: Converts salt into chlorine to sanitize the water.
  • Control Unit: Manages the chlorine levels, allowing adjustments based on the hot tub's needs.
  • Test Strips: Used to monitor water's salt levels and chemical balance.
  • pH Balancers: Essential for maintaining the optimal performance of the saltwater system.
  • Salt: Specially formulated for saltwater systems.
  • Owner's Manual: Guides through setup and maintenance processes.

Salt Water Chlorine Generator

The salt chlorine generator, also known as a salt water chlorinator, is the heart of your conversion kit. It uses electrolysis to convert salt into chlorine, which then sanitizes your water. You add salt to the water, and the generator does the rest, keeping your hot tub clean and clear.

Control Unit

Your conversion kit will include a control unit. This device allows you to manage salt water chlorine generators. You can set it to produce more or less chlorine, depending on your hot tub's needs. It ensures that your water stays at the perfect level of cleanliness.

Other Essential Accessories

  • Test Strips: You'll use these handy strips to keep an eye on your water's salt levels, chemical balance, and other parameters.
  • pH Balancers: Your water's pH must be balanced for optimal performance of your saltwater system.
  • Salt: Specifically formulated for saltwater systems, you'll need this to get started and maintain adequate salinity.
  • Owner's Manual: This manual will guide you through the setup and maintenance process, making sure you use the kit correctly.

How To Install Salt Water Chlorinators

How To Install Salt Water Chlorinators

To install salt water chlorinators, select the appropriate kit and remove the hot tub plug. Install the salt system cartridge as per the kit type—inline or drop-in. An inline kit integrates directly with the hot tub's plumbing, while a drop-in system is placed directly into the water. Refill the hot tub, add the specified amount of salt, and activate the system. Regularly monitor and maintain water balance and salt levels post-installation.

Here is a more detailed list of the steps you need to take:

Pre-Installation Checklist

  • Test Water Balance: Check and adjust your hot tub’s pH, alkalinity, and calcium hardness.
  • Clean Your Tub: Thoroughly clean and drain your hot tub before conversion.

Step-by-Step Guide

  1. Select the Right Kit: Choose either a drop-in or in-line saltwater generator based on ease and preferred installation method.
  2. Remove the Hot Tub Plug: Before installing, make sure you remove the existing plug.
  3. Insert the Salt System Cartridge: For in-line systems, install the generator according to the manufacturer’s guide. For a drop-in system, place the cell in the water.
  4. Fill Your Hot Tub: Use a garden hose to fill through the filter compartment until one inch above the highest jet.
  5. Add Salt: Refer to your kit's guide for the correct amount of salt.
  6. Turn On: Activate your system and let it run. Check if any indicator lights are on.

Post-Installation Tips

  • Regular Monitoring: Keep an eye on sanitizer levels and system indicators.
  • Maintain Water Balance: Regularly test and adjust pH, alkalinity, and calcium as needed.
  • Add Salt as Directed: You'll only need to add more salt occasionally, when the system indicates or after heavy spa use.

Maintenance of a Salt Water Hot Tub

Maintenance of a Salt Water Hot Tub

Maintaining a salt water hot tub is straightforward if you follow a consistent routine. The right balance of salt and clean equipment will ensure a pleasant experience.

Regular Maintenance Tasks

You need to check the salt levels and inspect and clean the filters as part of your regular hot tub maintenance.

1. Check Salt Levels

You need to keep salt at the ideal concentration. Most salt water hot tub systems require about 2 pounds of salt for every 100 gallons of water. Check your system for accurate amounts. Use test strips to check the salt concentration every week.

2. Inspect and Clean Filters

Clean or replace filters as needed to keep the water clear. Most filters need a rinse every 2-4 weeks and a deep clean every few months.

Troubleshooting Common Issues

The most common issues in maintaining a saltwater hot tub are cloudy water and warning indicators. Here is how to manage them:

Cloudy Water

If your water turns cloudy, check and adjust salt levels, clean the filters, and make sure the generator is working.

Warning Indicators

If indicator lights turn on, add salt as required. If problems persist, consult the user manual or contact the manufacturer.

Recommended Salt Levels

The optimal salt range for hot tubs is the following:

  • Soft Tubs: 1,750–2,000 ppm
  • Standard Tubs: 2,000–3,000 ppm

Always refer to your specific model's manual, as each system may vary slightly in recommended salt concentrations. Use a saltwater test kit for accurate measurements.

Best Practices for Salt Water Balance

Best Practices for Salt Water Balance

Maintaining the correct salt water balance helps your hot tub last longer and comfort its users. Regular balance tests and adjustments ensure a clean and pleasant spa experience.

Test the Water Chemistry

Test your water regularly to monitor pH and sanitizing levels. Ideal pH levels range from 7.2 to 7.8. Use test strips or a digital hot tub water tester. Record your results to track trends over time.

Adjust Salt Levels

Ensure that the salt level stays within the range specified by your saltwater system manufacturer. Too little salt will not generate enough sanitizer, while too much can damage the system. Add salt according to the system's readings, typically when the indicator lights up.

Apply Shock Treatments

Perform shock treatments weekly to remove organic contaminants. This restores the clarity and sanitizing efficiency of your hot tub water. Follow package instructions for the correct amount of shock to use. Try a hot tub non-chlorine shock if you don't want to use a lot of chemicals.
