1. ControlOMatic ChlorMaker Saltwater Chlorine Generation System

The ChlorMaker Saltwater Chlorine Generation System is especially for spas or hot tubs with a ten-foot weather-protected GFCI 110 or 220 volts outlet. I like that it is a plug-and-play model and semi-automated.

Moreover, it does not need the tub to be in operation for it to generate chlorine, and it operates on a three-hour cycle. The salt-water system can produce chlorine eight times daily. However, it is not waterproof, and I had difficulty figuring out the right setting for my spa.

Specs

  • Plug and play
  • Generates chlorine for a maximum of 1,000 gallons of water
  • Ten levels of chlorine generation
  • Up to 30 grams of chlorine product daily
  • Add-on: Concealed installation kit for 220-volt environment
  • Visual salt level indicator
  • Automatic boost of chlorine production for heavy spa use
  • Self-cleaning

Pros

  • No chemicals needed to clean hot tub water
  • No regular monitoring of pH or chemical levels
  • Excellent customer service

Cons

  • Not waterproof or weatherproof
  • Challenging to determine the correct power settings for your hot tub

You may want to try the ControlOMatic ChlorMaker for your salt-water hot tub if you’re after fresh and clean water without the harsh chemicals.

It can produce 30 grams of chlorine daily and can process a maximum of 1,000 gallons of water before you have to change it. It’s also a self-cleaning device with an uncomplicated installation process. It’s an excellent, all-around salt-water chlorination for your hot tub.

2. Saltron Mini Salt System Saltwater Chlorine Generator

I like the Saltron Mini because it uses the saltwater conversion technique for chlorine generation. Diluted salt passes through a chlorine cell as the electric current breaks it down into hypochlorous acid and hydrogen. The former provides the sanitation and converts back to salt form for reuse by the system later.

This mini salt system is suitable for spas, hot tubs, and small pools. Moreover, it has a small digital display and control panel with LED lights that indicate the salt level and buttons to turn on, off, and program the timer.

The digital timer makes it more convenient because it can automatically turn on and off the chlorine generator at preset times. Moreover, it has a scale prevention feature through the cell that reverses in polarity to prevent its formation. However, if there’s one complaint that I have about this product, it will be its poor after-sales customer service.

Specs

  • Uses saltwater conversion technique
  • For small pools, hot tubs, and spas
  • Digital screen control panel
  • Scale prevention feature
  • Digital timer
  • Drop-in style
  • Manual or automatic operation

Pros

  • Convenience and ease of use
  • Skin-friendly and non-irritating to the eyes salt
  • Eliminates the pungent chlorine smell
  • Cost-efficient

Cons

  • Bad after-sales customer service
  • Very short power cord

If you’re searching for a drop-in saltwater chlorine generator system for your hot tub, you may want to try the Solaxx Saltron Mini. You can submerge the cell in the water, so you don’t need any specialized plumbing works or pool pumps.

However, you may also do it manually by turning the generator on using the control buttons and turning it off when the salt meter displays a regular reading. Another thing that you may like is its scale prevention mechanism for simple care and maintenance.

3. Intex Krystal Clear Saltwater System with ECO (Electrocatalytic Oxidation)

I like the Intex Crystal because of its two-stage water sanitation technology. It provides swimmer-safe chlorine upon adding table salt into the hot tub or pool. A filtration process occurs that produces fresh and clean water without the potentially harmful effects of chemicals.

The saltwater system has an electrocatalytic oxidation (ECO) process that splits water molecules into oxidants that destroy algae and bacteria and reduces the amount of chlorine required by as much as 60%. However, it requires a filter pump with at least a 700 GPH flow rate.

Specs

  • Suitable for 7,000 and 15,0000-gallon water capacity pool
  • Chlorine output at 12g/hour
  • Self-cleaning cell
  • Status LED indicators
  • Ability to boost water chlorination
  • Two-year warranty
  • Best for above ground pools and hot tubs

Pros

  • Easy installation
  • Straightforward operation
  • Prevents calcium buildup on the cells
  • The transparent chlorinator cell housing
  • Easy to clean cell plates

Cons

  • Requires a filter pump with a minimum 700 GPH flow rate

The Intex Krystal Clear is a breeze to install; therefore, if you’re after the ease of installation, you may want to try it. You have to attach the hose from the pump output to the unit; then, you have to connect the other hose from the chlorinator output to your hot tub.

You won’t have any issue with maintenance because of its self-cleaning function that prevents calcium build up on the plates. You also have quick access to the cell because of its transparent chlorinator housing. Cleaning is also effortless because you can use a pre-made or acid solution to clean the chlorine cells.

The infinite cycle makes the water refreshing and sparklingly clear. I also like that its fully automatic, economical, and easy to install. It’s suitable for spas, hot tubs, and swimming pools of a maximum of 20,000 gallons.

The Solaxx Saltron Retro can release pure chlorine from ordinary table salt. Moreover, it has a programmable digital timer for chlorine generation. However, it’s not suitable for pools with top-air rings.

  • Programmable digital timer
  • LED indicator lights for salt level
  • Titanium cell plates
  • Reverse polarity to maintain cell cleanliness and prevent scaling
  • Transparent cell housing

  • 1,500 gallons per hour system flow rate

Buying Guide For The Best Salt Water Hot Tubs

You may consider some of my suggestions in buying the best salt water hot tubs.

Pool Size, Type, And Usage

You have a wide range of options when it comes to chlorinators, but you have to understand that some systems work on a particular pool or spa type only.

You also have to determine first the size of your hot tub and its water capacity. Moreover, you have to consider pool usage according to the season.

For instance, you have to determine the average usage during summertime, so you don’t underestimate your need for chlorine.

If you’re using your tub daily, you need more chlorine. You have to compute your requirements correctly to maintain the safe pH level of your spa throughout the year.

Offline or Inline Chlorinator

If you have heaters and filtration systems, you may want your chlorinator to connect to them; so, you have to search for an inline model.

However, you may prefer an offline system that bypasses your existing pool equipment network and connects using a separate line.

If you prefer the inline type, you have to put the chlorinator system as the last equipment piece to clean your hot tub water thoroughly.

Durability and Reliability

You may have a harsh climate where you live; thus, you have to see professional advice when you buy a saltwater chlorinator system. The cell must be of high quality because it wears out the fastest. Moreover, you have to consider ease of maintenance when buying one.

You may opt for self-cleaning or a standard model. You also have to check for the warranty and the cost-effectiveness of the system that you intend to buy.

Power Supply

The power supply energizes the salt cell to produce chlorine. If your control panel has push buttons or a rotary dial, you can set the output level from 0% to 100%.

Some models allow you to set the degree in 1% increments for a fine-tuned chlorine production to match the operation of your hot tub.

The power supply also provides electricity to the indicators or warning lights, so you know if there are damaged components or improper operating conditions.

Final Thoughts

I recommend the ControlOMatic ChlorMaker because it’s plug-and-play and fit for spas. You don’t need to turn on the tub for the system to produce chlorine because it can operate on a three-hour cycle. You get fresh and clear water without the harshness of chemicals.

The saltwater system can produce 30 grams of chlorine every day for up to a 1,000-gallon water capacity spa. You’ll also like that it’s self-cleaning and easy to install.

You’ll gain all the benefits of the best salt water hot tubs, and if you have any issues, you’ll be happy with the excellent after-sales customer service that the company provides.
