pour the fixer back into the 1-gallon bottle and use until it is expired. You know it is expired when it takes longer than 5 minutes for the milky look on your film to clear. When it does, dump the fixer out of the film container and into the sink, pour more in from the gallon, repeat until the film is clear (it will) and then dump the rest and mix new.
