I've never heard of ozonated water or the Tersano Lotus system before. They sure have blanketed the web with positive text but it would be interesting to see what conservation testing such as an Oddy test would show up. Ozone itself is a strong oxidizer and has lots of other health related problems. On the good side, it reverts back to O2 quickly. You might want to post this query on the PACCIN Listserve as well as that tends to get more response since it comes to people instead of them having to check this site. I look forward to what others have to add.
