Spa Ozonators 101

Spa Ozonators 101

An ozone system helps keep your water clean without the need for chemicals by injecting ozone gas into your spa water. Hot tubs with ozone sanitation systems are easier to use and maintain. And ensure your system is operating properly and providing the best quality water.

Ozone not only destroys microorganisms but also breaks down hazardous chemicals, causing total dissolved solids to clump together for easier removal by your filter cartridge.

For almost as long as spas have existed, Ozone automatic sanitiser (or oxidizer) systems have existed in spas.

Ozone Purification Systems

Ozone is a powerful oxidizer of contaminants in water, made available for hot tubs and spas through ozonators. When ozone is injected into spa water, it destroys most bacteria and viruses present. In newer ozonators, ozone gas is created when three atoms of oxygen are joined together rather than the normal two.

Ozonators split oxygen molecules in one of two ways: intense ultraviolet (UV) light or using what is known as a corona discharge (CD) unit. Ozonators convert oxygen molecules into two free oxygen atoms.

Ozone is reactive and breaks up chlorine and bromine molecules that have bonded to contaminants. This frees up the sanitisers so they can be reused continuously, saving you money.

When these freed oxygen atoms collide with existing oxygen molecules present in the water, they create ozone.

Also when it comes to other insects such as roaches and fleas, ozone generators can destroy fungus and mold.

Ozone Sanitising Systems for Spas

If left unchecked, spa water can become very dirty and concentrated with grime. To help ensure that any bugs that penetrate the water are quickly neutralized, every spa should be fitted with a safe sanitizing system.

Spa ozone is the most effective oxidizer and disinfectant that can be used in spas. It kills all known bacteria, viruses, yeast, and a few other things you may not want to hear about.

An ozone generator converts Oxygen (O2) from the atmosphere, into Ozone (O3) in your spa. (O3) means that there are now 3 Oxygen molecules. Oxygen is an Oxidiser and when (O3) comes into contact with microscopic particles in the spa water, it dissolves those particles.

What Ozone Generators do in Hot Tubs

  • Reduce the need for high chemical doses
  • Assist in destroying bacteria, viruses, algae, yeasts
  • Oxidizes other contaminants
  • Produce less odour and chloramines
  • Prolong the spas equipment lifespan
  • Reduces maintenance time and cost
  • Offers a natural purification method

Other Ozone Benefits

Ozone cleans water by destroying microbes and oxidizing contaminants. This makes it easier to remove impurities from the water, resulting in cleaner, clearer, and smoother-feeling water.

Ozone also oxidizes soap, deodorant, hair spray, cologne, perfume, body cream, sun tan lotion, saliva, and urine, which can be used in conjunction with your sanitizer.

Ozone helps chlorine and bromine work better and last longer. It also makes alternative sanitiser systems more effective. Less chlorine or bromine may be needed! Water quality will also be dramatically better with the combination of ozone and chlorine/bromine than with chlorine/bromine alone.

Ozone FAQ

Can Ozone replace my current sanitiser?

The answer is no. Ozone has a very short half-life in water, making it ineffective as a sanitiser. You will use fewer chemicals, often 25% less. This pays for the ozone system over time and makes spa maintenance easier. Actual reductions will depend on many factors, including water quality and bather load. Many people report that their spa water feels softer to the skin!

How long should I operate my Ozonator each day?

You should run your ozonator for at least 2 hours, twice a day. This will be the most effective. However, check your spa owner's manual and follow its recommendations.

Can an Ozonator system be added to my hot tub?

Yes, 90% of all new spas are "ozone ready". They will only require the installation of an Ozonator kit.

Is Spa ozone safe for me and the environment?

When dissolved in water, Spa produced Ozone is completely safe. Excess Ozone will convert back to oxygen. The amount of ozone produced by a hot tub ozone generator is negligible to the normal atmosphere we live in.

Does Ozone Affect my Spa Water Ph?

Ozone is will not adversely affect the pH of your hot tub water. This is because Ozone is pH neutral. 

Are all Ozone systems the same?

Not all ozone systems are the same. Make sure the system produces enough ozone and that it mixes and dissolves well into the water. The ozone should also revert back to oxygen by the time it escapes to the surface of the water. A high-performance Corona Discharge Ozone Unit, combined with an efficient Venturi Injector, are keys to this process. The plumbing method used to incorporate this into the spa is also critical.

How Often Should You Run Your Ozonator?

For best results, run your ozonator continuously, especially if you use your hot tub frequently. Depending on bather load, you may need to run it for 3 hours during a 12-hour period, or up to 24 hours a day.

Summing Up

Spas with ozonator systems can keep your water sparkling and healthy while reducing your expenses. You'll save money on chemicals, enjoy cleaner, healthier soaks in your spa! You'll save money on chemicals, cleaner, healthier soaks in your spa, and you'll be able to shock less often!
