Northern Reefer
I bought a reefractometer 2 weeks ago to replace my coralife hydrometer and I want to make sure I am measuring my salinity corectly
I calibrated my refractometer with RODI water and it is reading 1.024, when I test with the hydrometer it reads almost 1.028
I am guessing the hydrometer is off or maybe something else?
