My refractometer is reading 1.026 while my hydrometer is reading 1.021.......Which one is more reliable? Does anyone know?? Dont know if I should try to bring my salinity down or not.My fish and my Anemones seem to be doing fine.
what brand of refractometer and when was the last time that you calibrated it? what brand of hydrometer? refractos are much more accurate as long as they are calibrated on a regular basis
