I was using a floating hydrometer to measure my salinity and it kept getting stuck which was ticking me off so I bought a refractometer. I figured it was a set it and forget it type thing didn't ever calibrate or even verify the readings with the float and carried on with my weekly water changes for a year or so. What I didn't realize is that the calibration screw is very easily adjustable and somehow it got twisted. Since I wasn't calibrating the meter it was WAY off and I accidentally lowered my salinity to 1.005 thinking I was fine at 1.025. Killed everything in my 90 gallon reef.
I now bought some calibration solution and check/ calibrate before every use.
