Maybe some of you know McNett´s "Aquamira"?
It´s a 2-K composit that works by oxygen and works very well for me when I´m on a usual trip.
On Brigade Quartermaster I´ve found "Aerobic Oxygen" - it´s only one liquid and they say it can kill even guardia-lamblia, which is the main reason for my to look for an oxygen-based chemical for watertreatment.

Does anyone have some experience with it ?

thanks
