Honestly the best thing you can do is invest in a refractometer and calibrate it with RO /DI water every time you use it! The floating arm hydrometers always get salty deposits and calcium deposits in and around the moving parts which will prevent it from working properly. I find them so useless that I don't have one in my tank I jet regularly check with my refractometer. They are not expensive and deffinately an investment in the long run! I would bet your SG is different from 1.026 with a refractometer reading, hopefully this will prevent any further loss - sorry about the shrimp!:-/
Very good information. Everyone says to get one but this is the first explination of why that has made any sense to me. Thanks.
