i have a storage container that has premixed saltwater in it, unfortunatly it has been sitting their with out and air mixing the water around for about a week, would it still be good or has it become stagnat?
HA HA, I'm in freshwater so I don't know much about saltwater... I am kind of leaning towards that the water should be still ok, just check parameters of that water and the salinity of it before adding to your tank.
Yeah, the only thing that could change is the water evaporation and pH change. So that why I incidated to check the salinity of the water so you don't get pickled fishy :joke:
