this is a new tub and I can’t get it to hold chlorine. It got real cloudy so I brought it up to school level last night and kept adding chlorine to keep it at 14 ppm.
11:30 last night FC 14ppm
6:30 this morning 1ppm (it is much clearer though

Sounds like you still have something burning your chlorine, but I find that in my swim spa the ozonator burns off about half of my chlorine each day.

That's the deal with ozone, you slam it with some chlorine and the ozonator eats it up for you. Keep adding heavy for a day or 2 amd it should clear and ne goos to go
