Sanitizing Water Tank

Slight hijack. From my time river rafting, where we filter and treat our own water right form the river, I have found many people object to the chlorine taste/odor after sanitizing the water with bleach. A friend of mine, a chemistry professor, told me that after using the bleach and waiting for the appropriate amount of contact time we could add an identical amount of hydrogen peroxide and that would counteract the bleach. No odor, no taste and pretty good water. Just a thought.
