Shelf Life of SW & RODI

[NanoCubeNewbie]

Anyone know what the approximate shelf life of saltwater and RO/DI is?

If it is in a sealed container, how long will they each remain usable for the tank?

hmm, I think RO/DI water would be fine for a while (just like regular bottled water) but it would have to be sealed really well so stuff doesn't get in it.
With saltwater, I would think that if it stays stagnant it wouldn't be good, with some flow would be better as I know of a lot of people who have gigantic quantities of saltwater waiting in case of an emergency.
