My hanna checker measures the salinity differently depending on the temperature.
When it runs at 79 degrees, it says the Salinity is 1.024, but when the water comes to room temp it reads at 1.028.
When I check the Salinity with a refractometer, it says 1.027.
Is the salinity in the tank really 1.024, or 1.028?
