The interesting thing about the chlorine dioxide is that it doesn't sterilise the water in the same way as hypochlorite. Chlorine dioxide (a dissolved gas), breaks down into salts, oxygen & hydrogen gas. It's the oxygen that oxidizes the pathogens, not the chlorine gas.

Do you remember when people were drinking bleach to treat COVID? Chlorine dioxide was also known as Miracle Mineral Supplement & was used in many poor countries to treat COVID. MSM have been demonising it, calling it bleach for a long time. It is used as a bleach & sanitiser in industry but at much higher concentrations.
