I see the Potable Aqua is being packaged with Vitamin C tablets to remove the iodine taste. I have heard ETS'ers mention doing this on their own as well. Does it really work? What's the theory behind it? Anybody have an opinion on if it would work to remove other objectionable flavors? I'm thinking specifically about ways to remove the plastic taste that commercially bottled water develops over time, and I'm sure there are others. It never hurts to have a little extra Vitamin C on hand anyway, and if it works I might include a small quantity with each case of water I store.
