I've been thinking about putting Aquamira into 2-1/2 oz. lighter bottles to save a little weight.
To those of you that have Thru'ed or are long distance hikers that use Aquamira, have y'all done this?
It seems that carrying treatment for 30 gallons of water at a time is just dead weight. I saw some 1/2 oz. dropper bottles at backpackinglight.com and think this is a good option.
