Ozone poses a threat to bathers?

Thanks Clover and Chemgeek for your comments , I was in the tub tonight and did not think about ozone at all, looked up at the northern stars and appreciated the serenity my hot tub in rural upstate N.Y. provides. I agree with you guys, if we keep our tubs in working order and manage the water , we all will be just fine. I know having this tub, has made my life a little more easy and comforting, due to the arthritis I have.

That is the best news ever....and that's the way it should be.  

Hot water soaks are the best.  We all wish, for more like you, to see the stars and enjoy your comforts.

Getting back to this old topic, I solved the "problem" by installing on on/off switch for the ozonator (previously the ozonator was always on, even with the massage pumps running). I simply turn the ozonator off before entering the spa and turn it on again after soaking. Simple and gives my peace of mind Didn't even cost much to have the switch installed.

Thanks for the follow-up.  It would be great if EVERY manufacturer including an ozonator would have a simple on/off switch so that one could disable the ozonator when desired.  Use of the ozonator makes sense when there is high bather load and is also useful in a bromine spa (since it can make more bromine from the bromide bank, though it makes bromate as well), but having the ozonator on during many days in between infrequent soaks when using chlorine is wasteful as it just uses up chlorine faster making maintenance more difficult.

Ok chem geek, so when I'm using dichlor together with Aquafinesse, how would you recommend me to use the ozonator?

[chem geek]

If you are using Dichlor in between soaks for disinfection, then if you have more than a day or two in between soaks then turn off the ozonator so that the chlorine will last longer.  If you are soaking every day or two then leave the ozonator on.  Basically, just see the ozonator as oxidizing both bather waste and chlorine so when there's no bather waste it just uses up chlorine faster than you'd want.

Ok, thanks for the tip chem geek!
