I've been calibrating my refractometer with RODI for the past 2 years. I now know that it's best to calibrate with calibration solution. I want to switch to calibrating with the solution with my next water change, but the problem that I ran into is when I calibrate using the solution my tanks salinity is crazy low (in the low 20's). But when I calibrate using. RODI it is right on at 34.
All is well in my tank with my fish and corals (with the exception of a slight battle with dinos.)
Should I continue to calibrate with RODI or should I switch to the calibration solution? If so, how do I switch without causing a crazy swing in salinity?
