MIOX uses a mixture of several oxidants including (it is assumed) both straight chlorine and chlorine dioxide. Since it will kill Crypto, and straight chlorine does not, it must have more (chlorine dioxide will kill Crypto). The exact mixture is not divulged by the manufacturer, and I have not looked at it in the lab.

The MIOX test strips are set for a specific concentration of "something" as a go/no go guage. This is a standard method for insuring enough of a chemical agent like this. If there is some left, then it is not being destroyed by oxidizing living organisms. What level was set and the specific chemical they are testing is not known to me. I just spent some time with the results of their testing and decided this was an acceptable tool for me. It is not my only water purification method, but in some instances it works well.
