Hi everyone,
My hanna salinity checker and instant ocean hydrometer give pretty significant differences. This is even after I calibrate the hanna checker. I am obviously inclined to trust the hanna over a hydrometer, but I just wanted to hear thoughts on this. The Hanna reads my tank at 33.5 ppt while the hydrometer reads at 38 ppt with no bubbles. I have had a fear that the hanna tester and calibration solution are just high in general, but I haven't heard anyone else with this issue. I just want to ensure I can trust the hanna checker. I have a refractometer, but my eyes really cannot focus on the refractometer long enough to get consistent readings.
Thanks,
Josh
