The bottled water is your control group. Test bottled, then tap/well, then tank. If it turns out all three shows ammonia, your kit is off. If it turns out tap and tank show ammonia, that's ammonia in your tap water, and the nitrogen cycle will take care of it just as if it came from a fish. You just need to allow for it and watch that it doesn't creep up past that amount, which means you are in a mini cycle. As long as you know your parameters, you can allow for them in your assessment of what to do with your readings. Good luck! I'd like to see how it turns out, the ammonia issue is interesting to me.
Edit: "If it turns out ONLY tap and tank show ammonia, then..."
With respect, you don't want distilled, then you have to end up adding minerals back in. Your best course of action is R/O water (almost all "spring water" in the grocery store is regular water purified with reverse osmosis). Your only issue then is watching that the pH isn't too low (most R/O comes in at about 6.5). IMO, distilled water is a very bad choice.
