Does mixed saltwater go stale

[pearsont74]

I mixed a 5gal batch of saltwater with my RO/DI system and its been sealed.....how long can i keep it before it goes stale or bad?

it won't really go bad, but you might want to put a powerhead or airstone in it to keep it circulating.

I`ve kept salt water up to a month before. I dont know what the max is. You want to let it set for a few days anyway after you make it .
