I recently got a digital salinity meter (Scionix) to replace my old refractometer.
I callibrated it with the fluid included in the package and I noticed that my refractometer was way off by comparison, so I began to slowly adjust the salinity of my tank. I also callibrated the refractomter with the fluid.
In the last few days I began noticing that something was not right with the corals.
I suspected the salinity could be the problem, so I made my own callibration solution with freshwater and table salt (963 gr of water + 37 gr of table salt).
I tested it with my refractometer: 1.025
I tested it with the digital salinity meter: 1.031
I tested the tank again:
Refractometer: 1.024
Salinity meter: 1.025
When I test the refractometer with rodi water it shows a value probably around 0.995. When I test rodi water with the digital salinity meter it shows 1.000.
What the heck is going on???
The nearest LFS is over 200kms away.
