Welcome to Backyardplus! In this post, we show you how to replace your hot tub ozonator with the Del Ozone UO3 ozonator on a Hot Spring, Tiger River, and Limelight spa. The DEL Ozone Spa UO3 model Ozonator uses CD (Corona Discharge) technology to create a high ozone output. The rated life span for normal use is up to 5 years, and this ozonator is rated for spas up to 1,000 gallons. The Del U03 reduces the use of chemical levels up to 90%, which means substantially reducing the amount of money you are spending to keep your water sanitized!

What is Ozone?
Unlike the Oxygen we breathe (O2), Ozone is a powerful oxidant made of three oxygen atoms (O3). The third oxygen atom in Ozone has a weak bond, which breaks off and destroys foreign bodies in the water. Ozone can safely kill pathogens, microorganisms, and both organic and inorganic contaminants through oxidation. Essentially, this is a natural way to keep your spa water clean that is much more powerful than chemical systems alone.
Let’s Get Started!
