Review on 🐠 SunGrow Refractometer for Aquarium Salinity Measurement - Highly Accurate, Calibration Tool Included, Promotes Optimal Plant and Marine Life Health, User-Friendly and Readability Enhanced by Janet Nelson

I ordered a refractometer specifically to check the salinity in my saltwater aquarium. I received a refractometer with a different scale than the one described. The chart in it was for sodium/chlorine on a 0 to 25 scale. I'm sure I can use it, but I don't have to try any conversions and hence loss of accuracy. I've also lost time on returns and tried to order a new one when it wasn't what was described in the listing.
