ok guys, I got a new hydrometer in the mail today from Ohio Brew stores. same as the one you get from NB. tested my saison that used 565 after 2 weeks in the fermenter and it reads at 1.001 (which is some DAMN whicked attenuation). however I checked it in tap water and it checks water as .995.. with it being off .005 are my readings totally fubar'd or do I just adjust up .005 points when I take my FG readings.
