I sometimes use the AM tablets for overnight water treatment. Maybe a slight chlorine taste but it doesn’t bother me in the least.
Even when there’s some of the chlorine smell/taste it doesn’t bother me, however as I’ve mentioned before I’m something of a knuckle-dragging Neanderthal when it comes to such stuff…. minor inconvenience if I’m really thirsty.
Review HERE of some of the tabs.
I have not tried Rex’s method of pouring the water back and forth in containers. But it makes perfect sense that it should help to aerate the water and encourage the off-gassing of any remaining chlorine.
However, I don’t filter and have been using AM liquid pre-mix for a few years as my main water treatment, mixed in a small, clear (well, translucent) 3ml bottle. I keep it in my shorts pocket or my pack’s waist pocket and haven’t seen the need for the black bottle. It still has that reassuring urine color all day and into the next, which the AM instruction sheet claims as the indication it is still potent.
Maybe I’ve just been lucky, but I’ve had to drink some very nasty swamp water a few times and have never gotten sick.
Sometimes it tastes more than a bit chlorine-y to me, although that generally occurs when I’ve put a full 14 drops into skanky water from a really bad source. Nice, clear flowing water that isn’t laced with lots of floaties sometimes gets only 6-7 drops and more time for the AM to do it’s thing.
