First things first, how do saltwater hot tubs work?

Central to understanding how saltwater hot tubs work is the role of the salt chlorine generator. This electronic device in all saltwater hot tubs transforms a very low level of salt, specifically sodium chloride, into chlorine through electrolysis. As spa water containing dissolved salt passes over the generator’s electrolytic cell, it activates a reaction that splits the salt molecules. This reaction produces a pure form of chlorine which then disperses throughout the saltwater hot tub, ensuring effective and consistent sanitization, while eliminating the chemical byproducts responsible for the caustic effects of chlorination.

This process of generating chlorine from salt is both continuous and automated, simplifying maintenance while ensuring the spa water remains consistently clean and safe. The elegance of this system lies in its ability to provide a steady level of chlorine, which is crucial for maintaining optimal water quality and offering an enhanced hot tub experience. Best of all, the salt in the water gets recycled over and over, so it doesn’t have to constantly be added.

The difference between saltwater and chlorine hot tubs

When considering the difference between saltwater and chlorine hot tubs, it’s important to focus on the chlorination process. Traditional chlorine hot tubs necessitate regular addition of chlorine, either in tablet or liquid form. This manual process requires continuous monitoring to maintain water quality, often leading to a vicious cycle of too-high then too-low chlorine levels; this doesn’t leave much time for enjoying the pool.

In contrast, saltwater hot tub systems generate chlorine in a more natural and seamless manner. The automated process ensures a consistent supply of chlorine, thus avoiding the common issues of over or under-chlorination. This not only minimizes the need for direct handling of harsh chemicals but also maintains a more stable and comfortable environment in the hot tub. This is because salt chlorine generators eliminate chloramines, which are responsible for the harsh effects typically associated with chlorinated water. This makes salt water hot tubs a more appealing option for those seeking a low-maintenance and user-friendly solution.

Bromine vs. saltwater hot tubs

Comparing bromine vs saltwater hot tubs highlights significant differences in the choice of sanitizing agents. Bromine, a popular alternative to chlorine, is chosen for its lesser odor and reduced irritation potential, yet it is more costly and slightly less effective. Saltwater systems, on the other hand, naturally produce chlorine in a way that eliminates the harsh chlorination effects, offering both economic and functional advantages. These systems also provide the unique benefit of softer-feeling water, greatly enhancing the soaking experience.

Notably, saltwater hot tubs offer a more natural soaking experience because they get rid of the formation of chloramines, the unpleasant byproducts of chlorine that cause issues like red eyes, itchy skin, and strong chemical smells. This advantage becomes particularly significant in hot tub settings, where the close and prolonged contact with water intensifies the need for a gentler, more enjoyable experience. The “saltwater” approach, therefore, not only improves the overall quality of the water but also contributes to a more luxurious and health-conscious soaking environment.

But what about the salt in the hot tub?

The level of salt required by a hot tub is extremely low (as low as 1500 ppm) - virtually at the levels of what is considered freshwater (up to 1000 ppm) when you compare it to what is technically considered “saltwater” (oceans are 35,000 ppm). This low level of salinity in the hot tub is safe and simply allows the salt chlorine generator to chlorinate the water via electrolysis. Even better, it doesn’t get depleted and is continually recycled, so the cost for salt is negligible.

Now that we've shed light on how saltwater hot tubs work, and clarified the differences between saltwater and chlorine hot tubs, as well as the distinctions in bromine vs saltwater hot tubs, it's time to delve into the heart of the matter. Without further ado, let's explore the 10 compelling reasons why converting your hot tub to a saltwater system is a decision you should consider today.
