Derek Posted March 13, 2010 Share Posted March 13, 2010 So, I discovered tonight that I did not calibrate my refractometer properly so essentially my salinity has been getting lower with each water change. I did two larger water changes this week which took my salinity down to about 1.021. My corals are not very happy right now. My fish are fine though. I have been attempting to raise the salinity by dissolving salt in RO/DI water. Is this the best way to do it? I haven't been trying to make it jump to 1.025, just trying to get it nudged in the right direction, maybe raise it up to 1.025 over the course of a few hours.
