When it comes to cleaning your hot tub you want something you can depend on that’s fast and powerful, meet Ozone, the superhero among the hot tub sanitizers. When Ozone comes into contact with an oxidizable substance in your hot tub – BAM – it’s outta there!

With Ozone, the oxidation process is incredibly fast. Chlorine and bromine cannot compete in the speed department when it comes to the destruction of microorganisms commonly found in hot tubs (think bacteria, viruses, spores, plankton and protozoa.) Yuck! Nobody wants those lingering around in their hot tub water! Ozone is also the strongest oxidant among disinfecting agents commonly used in hot tub maintenance, beating chlorine and bromine once again.

So powerful, in fact, it’s able to destroy a wider spectrum of organisms than either chlorine or bromine. Algae: gone. Body oils: gone. Sweat: gone. Not to mention, Ozone also picks up those unfavorable byproducts of chlorine …byproducts such as chloramines and chloramine precursors… those little leftovers Chlorine leaves behind as it does its jobs.

Let’s turn on the slo-mo and take a look at what really happens when you turn our superhero, Ozone, loose in the hot tub

What is Ozone?

Ozone is the tri-atomic form of oxygen (O3). It is a colorless unstable gas with a strong odor. Ozone is formed by either electrical discharge or ultraviolet light. In our hot tubs it is formed by an  electrical charge and it then introduced into the water as a gas, where it does it’s magic. Ozonation is the name of the chemical process in which the Ozone is added to your hot tub water.

How does Ozone work?

When the Ozone molecule encounters an oxidizable substance in your hot tub water, an oxidation reaction takes place. That is, the third oxygen atom of the molecule breaks away and attacks the substance, oxidizing it. The actual disinfection occurs as the oxidation reaction damages and destroys critical components of the microorganism.

As the third oxygen atom leaves the Ozone molecule (O3), it leaves two oxygen atoms remaining in the molecule (O2), which bears zero impact on water balance, all while unwelcome substances are destroyed – unlike Chlorine, which leaves chloramines in its wake. And remember, Ozone cleans that up, too!

All this remarkable power results in an extremely handsome superhero with a well documented list of helpful benefits, including elimination of organic and inorganic contaminants, killing harmful pathogens (including chlorine-resistant cryptosporidum), improved water clarity, destruction of plumbing build up, chloramines control, and reduction of supplemental sanitizers (chlorine and bromine) by 50% – 75%, a factor that can vary widely depending on a number of key variables.

So why not use just our superhero, Ozone, and give all others the boot? Well……as it turns out, as fast and powerful as Ozone is, it’s also very unstable – meaning that the three molecules of oxygen (O3), do not hang together for very long.

Though Ozone as a sanitizer in a hot tub is strong and fast, it alone cannot be considered adequate for proper sanitation in hot tub maintenance. We must also supplement it with an additional sanitizing product such as bromine or chlorine.
