I'm looking to get into some more detailed preparing. I have my feet wet on my limited budget (college student) and I want to maximize my water storage while minimizing my space.
Currently I am looking at getting 1-2 of these:
I hear good things about them, and feel 10 gallons should be good to have on reserve for myself and my girlfriend should the time come that I would need them.
My question though is this: If I chose to store ordinary tap water, how long could I expect it to last? Alone? With a bleach additive? How about with a more expensive "water preserving tablet" (I'm not familiar with these but I know they exist).
Also, is using ordinary tap water a good idea? If not what is a better alternative.
