Self pre-mixed saltwater shelf life?

[Jlavine]

If I make a fresh 5g batch of ro/di saltwater, how long can I store it in a plastic sealed jug in the closet?

I think it would be better to have a loose fitting lid on the container and an airstone in the container. Although I've never really stored mixed salt for longer than a few hours, I do know some people who have water around for days.

Google that if your serious for a accurate answer. I say it has a shelf life, decent one too. They sell boxed seawater that sits for who knows how long.

If you check the salinity before using shouldnt it be ok

If it gets air and light and no circulation it will go bad
