I use a 3l bladder in my bag (golite vo24) and carry at least 1 other item for water should the bladder develop a hole.

about the aquamira - I use a filter, I don't have enough patience to wait, especially on a hot day and water is low. Fill, add tablets, wait, drink, fill, add tablets, go. Does it effervesce? I use Nuun for electrolytes, but it doesn't work well in a sealed bottle.
