Does Your Spa Ozone Generator Need Replacement?
Maintaining clean and clear spa water can be a challenge for even the most experienced spa owner. Most spas are built with an ozone generator which works with chlorine and bromine to create crystal clear water that is safe, sanitized, and readily enjoyable. Yet, what happens when you find your water chemistry out of balance and your water cloudy? It might be time for an ozone generator replacement.
Why Do You Need a Spa Ozone Generator?
Your ozone generator plays a huge role in the quality of your spa water. As ozone is injected into the spa water, it offers a number of benefits:
- Ozone kills 99.9% of all viruses and bacteria.
- Ozone reduces the need for chemicals by up to 90%.
- Ozone breaks down oils, cosmetics and human contaminants.
- Ozone water purification is 200 times more powerful than chlorine.
- Ozone does not give off the chemical odor normally found in pools and spas; in fact, it breaks down the byproducts of chlorine and bromine that do cause such odors.
- Unlike traditional chemicals that can cause skin and nasal irritation, ozone does not.
- An ozonated spa requires fewer water drainings than a spa with other sanitizing chemicals.
How to Tell if It’s Time to Replace Your Ozone Generator:
Figuring out for yourself if your ozonator needs replacement is not as simple as you might expect. Some people will tell you to look for an “on” light or “check for bubbles” and, for sure, these checks may help you determine if the ozonator is on, but it doesn’t necessarily tell you if the ozone generator is producing ozone. A spa ozone generator may keep running long after it expires (stops producing adequate ozone) so you will need to look at other factors besides just power to the ozonator.
Assuming your ozone generator has power, the key is determining if the ozonator is producing enough ozone to be effective. When an ozone generator is near its expiration the ozone levels it produces may not be high enough to keep your water looking and feeling its best.
Ask yourself:
- Does your water look and feel like new? With a working ozonator and the proper chemical balance, it should.
- Do you find yourself continually upping the amount of chemicals you use in an attempt to fix your water quality? This is typical of spas that need an ozone generator replacement.
- Are you having trouble balancing your water chemistry? Adding chemicals may just add to the problem. Check your ozonator.
Have you replaced your spa ozonator in the past 3 years? If not, it’s likely your ozonator is expired. Ozone generators typically last 3 years.
Now what?
If after answering these questions you think you may need a new ozone generator for your spa, it’s best to call a technician who can perform an ozone test and recommend the right spa ozone generator. On the other hand, if you are a do-it-yourselfer and comfortable with replacing your own ozonator, shop our spa ozonators now.
