Thank you Bruce, are you saying that you would basically use 1 cup of water to 1 cup of flakes? I actually already mixed 1 cup of flakes to 3 cups of water, but I haven't used it yet because I wasn't sure about the dosage. Do you do the same with the citric acid crystals? 1 cup crystals to 1 cup water? I thought I could just mix this myself, as I am an herbalist, so I am always mixing up concoctions. But, this is a little different and I guess I am worried about doing it wrong. The good news is that I am not sick, this is just preventative. I use to get this in capsules years ago and I lost contact with the person who was making it. I did get some calcium hypochlorite capsules, can you take those? I have read quite a bit of Jim Humbles website, but I guess until you have some experience it is a bit confusing.
