Hey fellow hikers, I have a question. I am planning on walking the AT startin in march and am unsure about water treatment. I dont want to bring a filter because of the weight and i can do without it on the trail. All my previous experiences, I used iodine tablets but thety are expensive and the othre water treatmentis that much more expensive. What do people think about using a couple of drops of clorox bleach in the nalgene? Any hbad health effects for using it 6 months and any other water treatment suggestions?
