Well, you've got some good stuff there, especially for those who don't know the differences (including effectiveness) between bleach, iodine, and chlorine dioxide. On the other hand, my concern wasn't really about the effectiveness of any of those mentioned, but whether or not the shelf life of chlorine dioxide varies between pill form and liquid form? Also, is there any significant difference exists between Potable Aqua chlorine dioxide tablets and Micropur chlorine dioxide tablets.

Cheers,
Eric
P.S. I Googled Micropurs' shelf life and came up with 10 years (assuming you don't repackage them). That's pretty good!
