*Refractometers are listed to be calibrated with RO/DI or Distilled water. There is some new information stating for best results you should use a Salinity Fluid like the American Marine Salinity Fluid. This will yield you much more accurate results.
How to calibrate with Salinity Fluid from American Marine: Take a couple drops and read your unit. You should read 1.0259 salinity or 35ppt. Adjust your unit to match one of these two numbers. Once you adjusted the refractometer is now fine tuned for saltwater salinity/ppt. If you read ro/di after calibration you will have a negative reading and that is completely normal, as the unit is fine tuned now for a saltwater tank.
