So I should put the calibration fluid on my refractometer and use the screw driver (if necessary) to tweak it until it reads 35 ppt/1.025?..................yes...make sure the water is @ 78 degrees,your readings will change with temp fluctuations, i do 4 water changes a month and check the calibration monthly
