We will discuss the life of ozone and the types of spa systems best designed for Spas or Hot Tubs
Ozone is a great addition to your spa. It works best in spas with small circulation pumps running 24/7. These small pumps only pull around 100 to 200 watts. They are used in high end spas like Sundance, Hot Springs and Dimension One Spas.
The life of ozone is around 20 minutes in an ideal conditions. If you have a basic spa with a pump that runs on 2 speeds (low for circulation and high for jets) you most likely are running the pump only 2 or 3 hours a day. This type of system (usually low cost spas or hot tubs) does not reap much benefit from an ozone system. It does help, but not the way a system that runs the pump 24/7 with ozone being introduced 24/7.
Ozone is introduced by an injection method into the spa or hot tub plumbing only when the pump is running.
Ozone is nice to have on a basic spa with a two speed pump running 2 or 3 hours a day, you still use less chlorine or bromine. A spa system with a 24/7 pump though, will use much less chlorine or bromine, because the ozone is being used constantly.
I will talk about other aspects of ozone in other posts
