Sorry this may be ultra dumb but no idea what to do. I bought a refreactometer from Brs. Callibrated it using the instructions and test water it came with. Now when i test my tank water it just stays on zero. No change at all. Could i be doing something wrong. (Ps its a new tank i just started couple days ago. Added 20 cups of insant ocean salt). The salinity can be at zero im sure and i have no idea what to do lol.

Was the calibration liquid 35ppt or 0? Sounds like you potentially calibrated 35ppt to 0.

Ahh i see my mistake. The bottle of liquid that came with it says 35ppt. Therefore i calibrated it using that liquid and so 35 was my zero. They shouldnt write "Calibration liquid" in big on the bottle lol. I thought thats what you use to calibrate the machine.

 

Thanks for the help??

It is for calibrating the refractometer, but to 35, not 0.
