If I recall correctly what Bill wrote, the amount of sodium sulfite is 50g or "a Chock Full'o'Nuts coffee scoop."(posted 8607 days ago)It's also pretty much a plastic film cannister full.
With films being improved since way back then, I've cut down on the sodium sulfite to 25g/L and often use the Rodinal at 1:50. This is for HP5+; modern TX should be about the same.
