Most spas come with an ozonator installed which is in charge of keeping your water fresh and clean, ready when you are. As your spa ages, so does the ozone generator. Slowly, you add more and more chemicals. Balancing water becomes a chore. The water is no longer inviting. Just like a car needs an oil change, your spa needs a new ozonator. Typical spa ozonators last 3 years. Check your spa ozonator today. If, indeed, it has seen better days, HotTubWorks can find you the right unit for your spa. Ozone kills microorganisms, gets dust out of your spa, and makes the water so crispy, you won't be gasping to get out. Slip out of your tub and cozy up; no shower needed.
