Benefits of a Salt Water Pool

Salt water pool systems are the only other mainstream alternative to chlorine pool systems which have been the dominant force in the swimming pool industry. However, salt water pools are becoming more and more popular. While they are slowly steadily gaining ground, salt water pools are never likely to overtake chlorine pools as the dominant force.

Although we compare salt water pools and chlorine a lot (this post compares salt water pools and chlorine pools), this article takes a very different approach by focusing more on the environmental impact of pools rather than for the benefits of the pool owners. We’ll in go in depth why you should consider salt water pools if you want to be more environmentally friendly.

Combining efforts is the way to go, and if more people can become more conscious of their efforts then it will all add up and truly have a significant, positive effect on the environment. Other ways to improve the environment is by utilizing solar pool covers instead of pool heaters, or using top pool heat pumps instead of heaters when possible. This will not only be cheaper for you, but require less resources.

Chlorine Pools

Chlorine tabletsTo understand the benefits of salt water have it is good to have some knowledge of how chlorine pools work (since we are making the argument for salt water pools). First, cleaning and maintaining a chlorine pool is no easy task. They need a decent amount of work and maintenance.

One of the biggest reasons they require a lot of maintenance is that they have a fragile pH balance. Salt water pool owners need to stay on top of their pH levels because if a pool has the improper balance then it can quickly develop ugly, green algae (if you have this issue you’ll want to check out some powerful algaecides here).

Although checking the pH balance is an easy task there are a lot of steps required to make sure that the pH isn’t changed too much.

For example, debris falling in the pool can easily change the chemical composition of the pool so chlorine pools need to be cleaned constantly. They also need to maintain a certain chlorine ratio. Finally, they need to be “shocked” about once a month which is not an easy process either!

All of these chemicals and cleanings have a negative impact on the environment – particularly the chemicals. Chemicals are naturally bad for the environment, and chlorine is no different. Unfortunately, chlorine pools have to buy a lot of chlorine in order to maintain the chlorine to water ratio. This chlorine and chlorine water can have a huge impact on the environment as the chlorine water goes down sewage drains and goes down to the ocean.

Although 1 pool won’t have a large effect, imagine the chlorine from hundreds of pools all meeting up at one ocean dum off. This can ruin the ecosystem of the ocean and create algae in the ocean water as well.

As we can see, chlorine can have a large impact on the environment. Fortunately, salt water pools have a much smaller impact and can be much more gentle on the environment.

Salt Water Pools

After going over chlorine pools now we can understand the benefits that salt water pools represent. Contrary to popular belief, salt water pools actually contain chlorine, but don’t require any direct chlorine added to it. Instead, they often use the best salt water chlorinator owners can afford to convert salt into chlorine.

Surprisingly salt water pools don’t even have that much salt in them and many people can’t even tell there is salt in the water. The salt is a lot less than that of the ocean — typically about 1/10th.

Because salt water pools use both salt and chlorine for sanitation they aren’t quite as delicate as chlorine pools. They both kill germs, but the salt helps stabilize the pool pH levels.

Salt water pool environments have a wide range of acceptable salt levels. Because of this flexibility they are very easy to maintain and don’t require constant up keep like chlorine pools. In fact, salt doesn’t leave the water environment on its own so you only need to add salt (quite rarely) while chlorine can leave the environment pretty easily and get into surrounding grass, ground, and plants.


Admittedly, even chlorine pools don’t have a large impact on the environment. However, what we need to keep in mind is that there are hundreds or thousands of pools in a community. The collective efforts can have significant impacts to the environment for any given ecosystem.

With this in mind, we hope that you were able to understand what we presented in this article and realize how salt water pools can help improve the environment. Buying one is a great first step to reducing your environmental footprint, and this in turn can lead to other daily decisions that also add up.

Salt water pools have tons of benefits, but being more environmentally friend is a huge plus as well. With so much going for them you should definitely consider purchasing or switching to a salt water pool system.

Thank you for the informative article and from the refreshing viewpoint in which you present it. We believe Salt Chlorination can be the Green alternative for having a Blue Pool. We have a slightly different approach to salt water chlorination where we remove the hundreds of pounds of salt in the pool water and isolate it to a self contained stand alone unit. The amount of salt is far less and generates even less of an environmental footprint. The system in fact overcomes the regulations and problems with salt water pools that many people complain and frown on. After running no less than a thousand service calls on salt water pool systems we can affirm this is a better way to accomplish salt water chlorination. In fact, pH in salt water pools is always a problem as the products of electrolysis not only create hypochlorous acid for pool sanitation (chlorine) they also produce by product that continually raises pool pH requiring frequent pH modifying to maintain functional and healthy pool balance for the system. This salt water problem has also been overcome with new patented salt water pool technology available from Chlorine Genie. Thanks once again for your article and the refreshing point of view…
