I put up tap water in 5 and 7 gallon containers and it keeps at least a year (I replace it then, just because). I put about a capfull (more or less) of plain chlorox bleach in the container each time I refill it.

I've also kept bottled water (in the hard plastic sport bottles) for years, and nothing grew in it....I actually sent one off after a few years to be analyzed.

I make the ADL soil themselves. And that makes me very happy smile
