you can get calibration fluid, i would bet the refractometer is correct, my deep six hydrometer was out 4 points, it was reading 1.023 when actual was 1.027, my snails stopped dying after i corrected the salinity.
mine too lol. poor little buggers. haha, thats why I'm glad I know how much my hydrometer is out, and glad to know I'm getting a refractometer for xmas
