Welcome to our forum.
I know there are two camps on the subject of Ozone. But I want to state that for me it works !
It was like a stale, musty, dirty sock odor.Since replacing the ozonator, it's fresh and mildly sweet.Very pleasant now.Tim
Thing of it was... I wasn't low on sanitizer. I had been shocking like heck to try to clear it up.But the ozonator put it over the top. Cleared up the water and converted to a clean smell.I have read that the ozone systems for spas have improved a great deal with the addition of the "mixing chambers" that keep the ozone in contact with the water for a longer period of time.I never dreamed it made such a huge difference in the water quality.

OK, great news that you are happy with your ozonator. However, you say you were adding more chlorine than ever. Is that to say you were shocking the water with chlorine. See the issue there is when the water contains chloramines, adding more chlorine does not help. That is when you add potasiummonopersulfate, or other names "Activate" "Spa Shock" "Renu" etc. This product burns out excessive organics, and turns the chloramines back in to chlorine, and TA DAAAaaa no more dirty sock smell, and no ozonater needed.
You and I are in the same camp.
See the issue there is when the water contains chloramines, adding more chlorine does not help.
Not so...shocking with chlorine destroys chloramines just as well as adding MPS non-chlorine shock. Both are strong oxidizers.
Yup. Dirty sock odor. I Experienced it once when I was low on sanitizer.
To shock with chlorine you HAVE to add enough chloring to reach a FAC level 10 times higher than the combined chlorine level. IF you don't reach this FAC level you wont be breaking down any of the combined chlorine, but will be adding to it.
