I've been using a Hanna Salinity checker for the past 2 weeks and use the Hanna calibration fluid to calibrate it. After calibration my tank measures 1.024 SG. Pulling out my old refractometer. I measure something 1.026SG. So I order Fritz refractometer calibration fluid. After calibrating the refractometer, the tank reads 1.026 on the dot. Hanna measures consistently low.
I know its not a big difference, and consistency is a bigger factor than the SG. But which one do you guys think I should calibrate to? What do you guys use?
