Shelf life od seawater

Seawater.....how long does it stay good in your refrig after bought....

From FAQ's at Ocean Plasma:

"Ocean Plasma® in 120ml and 1 L bottles has a shelf life of no less than five (5) years. It is suggested, nonetheless, to keep purchased Ocean products in a refrigerator. When opened, it is recommended to keep this product cool and to consume it within 3 months. "

how many milions of years the sea water stay good inclusive with this human crazyness of pouring milions and milions of tones of any shit imaginable on it???

so if your "ocean plasma" is sea water and nothing more will last in your refrigerator milions of years ready for enjoy it. well in 1 or 2 milenia maybe the bottle break (glass) or is dissolved (plastic).

I have in a plastic bottle in a hot storage 5liters of 6 or more years and occasionally I give a look and at first glance is the same water.
no bad odour, no precipitations...
