hello, I haven't found any answer about my question around the net, so if you know the answer I will be thankful, I live in asia, and we have to add acid to dissolve the H#3, we don't have sterile citric acid or Vitc, like in the exchange program in uk, so we only have lemon juice, that is in the yellow bottle shaped lemon, and food grade citric acid, I've heard about getting an eye infection in a lot of threads around the web, but we got heavy and old H#3 Users, wich don't have an eye infection or never have seemed to heard of someone getting it, and a lot of them told me they use lemon juice, so my question is to where I live where we don't have sterile citric acid sachets or vitc, what should we add to dissolve ?
