Chemical-Free Hot Tubs?

Do you ever wonder if there is such a thing as chemical-free hot tubs? Maybe you’ve seen the signs driving along I-25 that read “Chemical Free Spas”? Unfortunately, some hot tub stores attempt to deceive potential customers by claiming that their spas require no chemicals. This is 100% false and a very dishonest tactic to gain sales. There are no such thing as chemical-free hot tubs. That being said, there are ways to reduce the amount of harsh chemicals required, down to a level that is virtually undetectable. But hot water without some sort of sanitization and oxidation will quickly become a petri dish filled with all manner of harmful bacteria and disease. If at least some amounts of chemicals weren’t necessary for a hot tub, why would anyone bother using them?

Aren’t saltwater hot tubs chemical free?

Salt (NaCl) or sodium chloride becomes sodium and chloride ions when dissolved in water. An electrode converts the chloride ions into chlorine gas, which kills bacteria. That’s right…. a saltwater hot tub is really just a chlorine hot tub.

Additionally, those electrodes only last between one and two years, even when performing regular cleaning (required). Replacement costs can be $800 or more! On top of that, the saltwater causes damage to your hot tub’s components. Salt is very corrosive. One major spa manufacturer even states in their owner’s manual that you should regularly hose down the area around your hot tub to avoid the build-up of salt from splash-out which can pit your concrete and kill your grass or plants. Salt systems are far from “set it and forget it”.  You also need to balance your pH, alkalinity, and calcium hardness. Salt systems are not chemical-free hot tubs and will not properly function with water that is not balanced.

Colorado Custom Spas was one of the first companies to offer saltwater systems for hot tubs. We have years of experience dealing with them. We will gladly install a salt system on any hot tub, though we will be up front and honest about the pros and cons of such systems. Luckily, we have found multiple solutions that offer the benefits of a saltwater hot tub, with none of the negatives such as corrosion.

Our most popular program uses a multi-faceted approach to achieving clean and clear water without any chemical smells or skin irritation. It also happens to be very simple, requiring about five minutes of your time once per month! A combination of ultraviolet light (UV), ozone gas, and minerals does most of the work. In addition to killing bacteria, the minerals help soften the water much like a salt system does. The amount of “chemical” in the water ends up being about one-half part per million (0.5 ppm). The EPA allows for up to 4 ppm of chlorine in drinking water, or eight times the level in our system!

Another natural option is our enzyme-based water treatment and conditioner. The enzymes inhibit bacterial growth and stabilize your pH. It contains lanolin and glycerin to soften the water, giving you silky smooth skin. One dose lasts for three months. Follow the link below to learn more.
