How long can saltwater sit?

You should be able to use it indefinitely unless it is somewhat contaminated, just make sure there is water movement (stirring). But if you use a salt without vitamins or other organic additives, you can store it unstirred if you want.
 
i mix up my 40 gallons in a large rubber made trashcan
then i toss my old power head 802/804 in there
there is more then enough water movement
