So I have been using the hanna digital salinity checker for my salinity readings for the past year or so and have consistently gotten a reading of 1.023 with an occasional jump to 1.024. I just bought a refractometer and tried it today and got a reading of 1.026. This is a day after getting a 1.023 reading with the hanna checker and not making any changes to the water. I guess the exact reading isnt that much of a big deal because my fish and coral have been completely fine and have never had any issues pertaining to salinity but just want to know going forward which device is gonna be better for the most accurate reading?
