What kind of oxygen tank and cylinder do I buy???is welding oxygen safe??

I have an ozone gen (oxytech) It is both a medical and non medical, has a pump to use air and that shuts off for use with oxygen. My question is what kind of oxygen tank and cylinder do I buy and how do I know the flow, am I just reading the cylinder?? Also to use it thru the ear and vaginal, I noticed some people add humidity to the ozone, how does one do that? Also what flow do I want to use thru the ear ? How about thru the vagina? Thanks so much. I have black mold and feeling sick lately. BTW I love this web site, its inspiring to read everyone's posts esp those that know and share their knowledge. Tweet
