The Best Salt Water Pool System in 2021

Saltwater Swimming Pool Resources

It takes work to maintain the sanitation and cleanliness of a swimming pool. That is why most pool owners hire a professional pool technician to do the maintenance work for them. Although that might save you time and effort, it won’t change the fact that unhealthy chemicals are getting put in your pool to keep it sanitary.

Have you ever noticed how chemical-based chlorine makes your eyes burn and sometimes even shortens your breath? Why subject people to these nasty side effects when you can clean your pool with a more natural chlorinator?

Salt water chlorinators are made to quickly and safely sanitize your swimming pool without the use of harsh chemicals. They also make pool sanitation much more affordable because you don’t have to keep buying new chemicals every month.

What is a Salt Water Chlorinator?

Salt water chlorinators are swimming pool water systems that use table salt to produce chlorine for the pool. A chlorinator can only function if the pool water has 3,000 ppm. Before you purchase a chlorinator, you must understand how a pool gets sanitized from the salt water chlorine.

Here is a basic rundown of this process:

  1. 1) Salt gets added at the bottom of the pool water. A brush might be used to dissolve the salt in the water.
  2. The chlorinator contains a control box or salt cell. The latter features parallel titanium plates with a ruthenium or iridium coating. If using a control box, it transmits a small amount of DC to the metal.
  3. When water flows through the cell, hypochlorous acid gets produced from the salt. It is the equivalent of putting stick chlorine or granular tablets in the water.
  4. When the hypochlorous acid circulates throughout the pool water, it will become healthier and more sanitary for users.

If you want to adjust the amount of chlorine produced for the water, all you have to do is press a few buttons. There are no special skills needed. The control panel has two buttons to adjust various settings for the chlorinator, such as the chlorine output, cell cleaning cycles and operating hours. The tracking feature lets you know how much time is left for the cycles to be completed. The Pentair 520556 Intellichlor Power Center is required to prolong the life of the IC20 Chlorine Generator Cell system. The chlorinator automatically deactivates to preserve its cell life for as long as possible, especially during low-temperature conditions.

The Pentair IntelliChlor IC20 is ideal for an inground swimming pool with no more than 20,000 gallons of water. It has received its UL 1081 certification and NSF approval.

The Top 4 Features of a High-Quality Salt Water Chlorinator

When you search for the best salt water chlorinator for your particular swimming pool model, you should look for specific features that make it an excellent model. These features include:

1) Strength and Durability

Any good table salt-based chlorinator system should have strength and durability. That way, it can withstand harsh outdoor weather conditions. Most saltwater chlorinators are easily susceptible to damage if they don’t have weather-resistant materials to protect them. Keep that in mind.

2) Control Mechanism

The ideal salt water chlorinator will have a control mechanism that lets you regulate the chlorine and pH levels of the pool. If there is too much or too little chlorine, an alert should be given to warn you. This will ensure that you have the best quality water flow and clarity possible.

3) Self-Cleaning Technology

Don’t purchase a salt water chlorinator that requires manual cleanings. Find a chlorinator with self-cleaning cell technology. The system will last for a much longer time, and you won’t have to spend as much time on maintenance either.

4) Electrode Lifespan

Find a salt water chlorinator with a long-lasting electrode. That is how you determine a chlorinator’s strength and capacity.

The Top 7 Considerations for Selecting a Salt Water Chlorinator

There are more considerations to make than just the features of the chlorinator. Below are the top 7 considerations for selecting the ideal salt water chlorinator for your swimming pool.

1) High Capacity

A powerful salt water chlorinator generator will have a higher capacity and chlorine output. If you have a larger pool, pay attention to the maximum capacity of the salt water chlorinator. It will also determine the amount of maintenance you will need to do regularly as well.

2) Pool Size

Find out how many gallons of water that your pool holds. Then multiply this number by 1.5 or 2. The final answer should match the maximum capacity of your salt water chlorinator. It is best to have a chlorinator with a higher capacity than your pool. That way, you can have peace of mind knowing that your pool water is getting cleaned.

3) Number of Users

ow many people will use your pool together? If you like to have pool parties with lots of people, then you’ll need a more powerful salt water chlorinator (even if your pool is small).

4) Environment

Hot environments tend to have a higher rate of evaporation. You’ll need a robust salt water chlorinator to compensate for the evaporated water. A powerful chlorinator also becomes helpful in environments with a lot of rainfall or dusty air.

5) Compatibility

Make sure your salt water chlorinator is compatible with your pool. If you know your pool model and size, then it will help you determine whether a chlorinator is compatible with it or not. Some of the older inground swimming pools have plumbing with iron pipes and copper. If these materials are exposed to salt water, they will form rust.

It is best to have a swimming pool made from fiberglass, concrete, tile, vinyl, stone, or plaster. These materials can tolerate salt just fine.

6) Longevity

Research which salt water chlorinators have the best longevity. You’ll want your investment to last for a long time. It is normal to have to replace the cell after a certain number of years. Aside from that, your chlorinator should last for several years with basic maintenance performed.

7) DIY Installation

Do-it-yourself installations are the best. Find an easy-to-install salt water chlorinator that does not require a professional installer. You will save both time and money.

The Top 8 Benefits of Salt Water Chlorinators

Are you still thinking about whether a salt water chlorinator is worth the investment? Below are the top 8 benefits of making this investment.

1) No Irritating Chemicals

You won’t have to use any irritating chemicals to clean your pool water. A salt water chlorinator uses table salt to produce non-irritating chlorine for the water. As a result, your clothes, eyes, and skin will not experience any adverse side effects. Salt water is more environmentally friendly than chemicals too.

2) Less Maintenance

Salt water chlorinators reduce the required maintenance considerably. You can enjoy more time in the water rather than outside the water. The beauty of a salt water cleaning system is that it self-cleans. Your responsibilities are to monitor the levels of pH, hardness and alkaline in the water.

3) No Foul Odors

Cleaning chemicals emit an irritating and foul odor. You won’t have that experience with salt water chlorine. The smell will be fresh and natural, which is why you won’t experience skin or eye irritations.

4) Algae Prevention

Salt water chlorinators do a better job of stopping algae before it forms on the surface of the water.

5) Affordable

Salt water chlorinators require a one-time upfront investment. After that, you won’t have to keep purchasing cleaning chemicals ever again. Your only future investment will be for the salt replacement. That is it.

6) Versatile Compatibility

Salt water chlorinators are compatible with multiple types of water devices and appliances. You can find chlorinators for swimming pools (large and small), hot tubs, spas, etc.

7) Easy to Install

Most salt water chlorinators do not require a professional installer. You can easily install your own chlorinator and save money at the same time.

8) Long Life

If you perform basic maintenance tasks on your salt water chlorinator, you should get at least 7 years of life out of it. You can expand the lifespan by consistently cleaning the cell, using the right salt level, and taking advantage of the reverse polarity technology of the chlorinator.

Final Words

Salt water chlorinators offer a plethora of benefits to pool owners. They allow you to avoid costly sanitation chemicals that cause irritation. Just choose from one of the many reputable brands, such as Pentair, Hayward, or Intex Krystal Clear.

Check the reviews of a particular chlorinator product to make sure other people have had positive experiences with it. If you can get at least 3 to 7 years out of your chlorinator, then it will still be a worthy investment.
