Susanj Posted May 13, 2020 Report Share Posted May 13, 2020 How does one know when an ozonator / ozone generator stops working In a hot tub ? I know with some spa models , you’ll see tiny bubbles when the jets aren’t on, but with our model it only comes in when the jets are on. The reason it seems important to me to know is because we were told the bromine level only needs to be at 1-2 with an ozonator but otherwise at 3-5 ppm.
