Everything You Need To Know About A Saltwater Pool

For a long time, saltwater pools were a hot commodity and latest trend. A number of hotels and resorts changed from standard chlorine pools to this new technology. And saltwater pools have become popular with their guests. Many people have changed to using saltwater in their home pools after staying in hotels that had them.  If you are considering installing or switching to a saltwater pool, you will first need to understand how these pools work and what it takes to maintain them so you can make the best choice for you and your family.

How it Works

Saltwater pools originated in Australia. They are very different from a standard chlorine pool. Here is a look at the step-by-step process of establishing a saltwater pool:

  1. Fresh water is turned into saltwater with a mild saline solution.
  2. A chlorine generator is added to the filtration system.
  3. Using a regeneration process, the generator circulates and chlorinates the water throughout the day. This process eliminates having to add chlorine and other chemicals directly to the water.
  4. The chlorine content in the salt works as a sanitizer.
  5. Saltwater pools use this repetitive process and, therefore, are in continuous rotation.


Saltwater pools require less maintenance due to the regenerative process of the filtration system. However, it is never "set and go." In order for the saltwater to continue sanitizing, it is important to clean the chlorine generator and brush the pool regularly to prevent algae and bacteria from growing.  

Pros and Cons

Saltwater pools are milder than a standard chlorine pool, making them ideal for people who easily get itchy eyes, runny noses, and irritated skin. Although there are great benefits to having a saltwater pool, there are also some negatives that go along with them. Consider what some pool and water experts told the Washington Times in 2009:

  1. Lack of maintenance and upkeep of the chlorine generator can lead to major problems such as bacteria and algae growth.
  2. Saltwater can cause damage to pool linings and equipment.
  3. Unbalanced chlorine and cyanuric acid levels can result in unhealthy conditions.
  4. Chlorine generators will increase the electric bill because they need to be on consistently.

If you are still on the fence about whether or not a saltwater pool is right for you, talk to a professional. A professional pool vendor (such as one from Nassau Pools Construction Inc) can offer expert advice on whether a saltwater pool is recommended in your area and discuss health and maintenance concerns in detail.
