Hey all,
I have a floating arm Hydrometer, and a Digital Salinity meter. I use to have a refractometer but it broke.
The Digital Meter says my tank is at 1.023 SG, the Floating arm Hydrometer says it is at 1.029 SG.
Which one do I believe? The digital Meter says its more accurate than refractometer's. But how do i know? The meter comes with a 30ppt calibration solution, and the meter shows 30ppt when put into the calibration solution.
Thanks,
-TheChad
