How Does a Saltwater Generator Work?

A saltwater generator is a sanitation system that serves as a substitute to a chlorine system. However, this doesn’t mean that saltwater pools are chlorine-free. These systems work by transforming sodium chloride (salt) into a chlorine susbstance. This is done by pouring salt into your water, with the system physically in the pool. This generator is able to convert that salt into chlorine that is then used to clean the pool. It does this with a process called electrolysis, which pulls the chlorine substance from the salt and injects that back into the pool water.

Overall, this chlorine is less pungent and harmful to people. This is because this chlorine is free of chloramines, which is often the cause of irritation in the chemical of chlorine. An absence of chloramines means that the system is a more expensive yet more clean way to sanitize your pool. There is less damage done to your pool and to swimmers with this system, but a higher barrier to entry. This is because most pool owners already spend plenty of money on their pool every year. However, there are a lot of reasons to be enticed by a saltwater generator and plenty of reasons to make the switch.

Frequent Questions About Saltwater Generators

Are Saltwater pools chlorine-free?

No. These pools still use a chlorine substance from salt in order to sanitize the pool. However, the chlorine is chloramine free and a lot cleaner. Also, much less chlorine is needed to sanitize the whole pool when related to chlorine systems.

How Much Salt is in a Saltwater Pool?

Only about 2500-4500ppm. This is relatively low when compared to the content of the ocean (around 35,000ppm). This salt content shows that it doesn’t take much salt to clean your pool. However, you will be able to notice that you are in a saltwater pool when swimming in it.

Can I Transform my Chlorine Pool to a Saltwater Pool?

Yes! If you purchase a chlorine generator it can seamlessly be added into your pool chemistry. This will often streamline your chemical treatments and save you a lot of labor time. However, you will still need to test your water chemistry and balance it as needed, especially with the addition of the salt reading in the water.
