Somewhere online you can find the dehydrated stuff. It's a lot lighter and takes up less space. just add water and it's ready to go.
:/
I forget the name of the tablets that work well too.
"Halazone" IIRC. One thing about all this iodine, clorox, halazone etc. I understand you shouldn't really drink water treated like this for more than a few days because eventually it will kill off the natural bacteria present in your digestive system and for some reason this is bad. Just what we were told when using halazone tabs years ago. I have no ready proof that this is true.
