We are going to be building a SWG pool. Is the ClearO3 recommended by this forum or is this something not needed. We had it in our last pool, but we also had a chlorine feeder. So I know it goes against a lot of what is on here. We did struggle with chemistry at times, so thinking about doing more testing and maybe trying to follow the method on here. But I know an ozanator can reduce chlorine needs which I would think would be good, but wanted to ask.
