Salt chlorine generators have long been a popular sanitation option for swimming pool owners, as they have been proven to be a safe, convenient, and inexpensive way to sanitize water. These benefits are now available for hot tub owners also.
Salt chlorine generators work as water flows through their "cell" the salt in the water is turned into Hypochlorous acid in a process known as electrolysis. Hypochlorous acid is the same thing that is produced when any chlorine is introduced to water, no matter what form it is introduced in. As the water enters the hot tub, it will introduce the newly produced chlorine which prevents algae, bacteria and micro-organisms. This creates a clean and safe bathing environment.
A common question about salt water systems is if this is a “salt” system is my water going to be salt water…like the ocean? Ocean water has a salt content of around 35,000 parts per million (“ppm”). Humans have a salt taste threshold of around 3,500 ppm. Most chlorine generator systems require a salt content of 2500 – 3000 ppm in a hot tub. Bathing in a spa with a salt generator is often compared to taking a shower in soft water; you should have no irritation and upon exiting the tub and your skin should feel soft and smooth. Bathing in a “salt water” spa should also cause less eye irritation than one treated with more traditional chemicals. In the beginning you will add salt to your water to get the system going but then because salt is not evaporated and is returned to the water from the chlorine it is very easy to maintain proper salt levels and the only time you would need to add salt is to make up for loss from splash out or when hot tub water is changed.
Here at Hot Tub Warehouse, we offer the Solaxx Saltron Mini Spa Chlorine Generator. This unit is very easy to install without requiring costly modifications to your spa. After installation you simply add normal table salt and the Saltron will produce chlorine used to sanitize your spa.
