Both Aquamira and Klearwater chlorine dioxide water treatment mixes say that after 30 minutes the water is ready to drink. I understand that this treatment time is long enough for viruses and bacteria ( I believe), but is it long enough for protozoa and cysts like giardia and crytosporidium. A few years back I bought a pack of Micropur water treatment tablets and it said on the package that you should wait 4 hours for giardia and crytospordium. Then I was told that 30 minutes is long enough in clear water. Any feedback on this would be greatly appreciated.
