    Is R/O water or Carbon Filtered water best?

    RO Water, as that is 0ppm (or near to), carbon filtered should be just the ion exchange, CA , MG ions exhanged to something else, mostly NA.
    But there is one type filter who do CA to MG.

    Edit: Carbon filter is just , filter, no ion exchange)
    Wrong info from me!

    RO is still 0 ppm :-)

    The further away you get from people/manufacturing, the cleaner the rain water is. Lots of places have chemicals in the rain water.

    Rain and RO are close. Neither are truly pure, and have miscellaneous insignificant ions in there. Both are pH neutral.

    Right, I dunno why but I always assumed water had a little but of X minerals in it, aLmost like it's raining calmag ;p. I feel dumb now ^^.

    On a side question. Collecting rain water with a barrel hooked upto a drain pipe etc. how safe is this type of water to use?, I'd imagine the rain water would pick up certain things when running off the roof or through the gutter system and also would it not stagnate if left in a barrel for too long?.
    Have been meaning to get around to collecting some rain water but that's what puts me off.

    Any water with organic material in it will start to decompose and grow algae. But fresh rainwater would only be limited by air pollution in your area.

    So would keeping it in the dark and using within a week be fool proof?.

    I think you'll be fine if it's a clean pail / drum and dark, as you said.
