So much BS around ozone it's staggering.....if the simple truth came out there would not be an AMA as we know it.
You need to get smaller tubing to adapt to the ozontor to hook it up to O2. We have adaptors for joining different tubing sizes, but it's better you email me directly to let me know what you need. I accept Curezone's rules and don't do not do commercial postings. I am glad you like the machine. It's a good deal for the money. I agree that o2-fed ozonators are a way better deal than air-fed ozonators, hands down. Just so much more pure and efficient.
