24 Hour Ozonator With Swg - Keep On Or Off?

[Bloomer57]

We just recently bought a 440 gallon Divine hot tub with 24 hour circulation pump and Del Ozonator. I really like the simplicity of chlorine and good experience with my pool swg so I decided to purchase a ControlOMatic ChlorMaker DO. I have recently learned how ozonators will oxidize the chlorine along with everything else, I just haven't been able to find the rate at which it will oxidize the chlorine. As far as bather load we will prob use it at least every night or every other night (1-3 bathers).

I have also read that the ozone can break down a spa cover faster, is this true? How much faster? Is this reason enough to unplug the ozonator?

With your using the spa every night or two that should be a higher enough bather load to have the ozonator be worth keeping on. It's only when the spa is used less frequently, such as only on weekends, when an ozonator will increase chlorine demand in between soaks so use up chlorine faster. With an SWG that may not matter anyway if you can have the SWG up high enough to overcome the ozone/chlorine reaction.

And yes you are correct that outgassing ozone breaks down spa covers faster. I can't quantify it -- it's just been reported (there are some spa dealers here who may know and can tell you). Up to you if you want to disconnect your ozonator.
