That's still only half of what I recommend. Hey if less works, go with less. Why waste. I use 30ml solely for the reason that I used to use 30 ml per gallon when I'd water my soil plants when I grew outside. It didn't harm them so I tried it inside with hydro. Worked fine for me so I've been recommending it since.
I've always been fascinated by the study of oxygen and ozone with regards to healing the human body. Its an amazing gas. Ozone kills ALL detrimental pathogens, viruses, bacteria, and fungus. It's an amazing gas. I've been drinking ozonated water for the last six months or so, and I have never, ever been so healthy.
For over 30 years doctors in Germany have been experimenting with ozone with all kinds of unbelievable results. Curing cancer, aids, all kinds of infectious diseases. Seems like Humans in general are suffering from " oxygen deficiency". It's a pretty interesting philosophy if you can wrap your head around it. And considering the fact that we deal with oxygen directly relating to the health of our plants everyday. You seem like people who can understand the fact that it's pretty damn important to maintain health. 95% of the diseases prevalent in society today are anaerobic. Meaning, they cannot survive with oxygen. That includes cancer, and Aids.
Conspiracy theory, or just common sense... what do you think?
