Funny u mention this ...refractometer calibrated (Red Sea calibration fluid) and reading 1.024 on my tank... a Buddy checked my water with his tests etc his refractometer (calibrated with the same product... Different bottle) came back with 1.019!! What would allow a refractometer to calibrate correctly but read so far off? Can't believe I lost $6-700 worth of SPS to something basic like salinity
