Hello
I want an ozone machine for a water pool about 8 cubic meters in order to replace the use of chlorine. I wanted to know that this machine is suitable for these needs and if so what size machine is needed and what conditions it needs in order for me to be able to use it.
The water temperature is about 50 degrees in one pool and the second between 25-30 depending on the temperature of the day.
And is it possible to bathe while the generator is working or not?
