    Important

    I know that this has been discussed before but I wanted to share an experience and how important it is to change calibration fluid. So over the last couple of waterchanges I started noticing my refractometer needed more calibration than usual. It wasn't reading 35ppt with the calibration fluid. I decided to order new calibration fluid as the last time this happened, calibration fluid was the issue. While waiting for the solution, the last week I have been having issues with some corals. My birdsnest and stylo started rtn'ing. My euphyllia,blastos, and plate were all retracted. All else fine. I couldn't figure out what was wrong. All parameters were good and stable. Just checked the salinity today as I got the new fluid in. Yup, my tanks were off and so was the refractometer.. 20g wasn't bad, 1.027 but normally 1.025 25g(where the problems were) was 1.030, normally 1.025 Checked the older calibration fluid 4 times. 40ppt Calibrated the refractometer with the new fluid and checked 4 times to make sure it was right 35ppt So 2 times I have noticed that once refractometer fluid gets to about 1/4 of the bottle left, it starts reading wrong. I corrected the 20g but I'm slowly lowering the 25g as there was so much of a difference. Gonna double check later all is ok and if not then maybe it's the refractometer needs replacing.
