I don't know about shelf life because I can't usually get through a month on just two bricks of film. I know it's supposed to be risky, but I store it in brown plastic 1 liter bottles (sometimes only half full, but the remainder gets used in the next couple of days) and I mix and dilute with tap water. I've been doing it like this for three years now and it's not failed me once.
