I'm currently mixing my Red Sea Coral Pro Salt (a.k.a. the only salt in the world that goes by weight instead of cups) and I when I mixed it in last night the ppt read 31 and the Specific Gravity read 1.022. However this morning ( when the pump wasn't running, it read 29 for the ppt, and 1.020 for the Specific Gravity. I am using a Milwaukee Electronic Refractometer and did calibrate it each time. So in short: Do the statistics of salt change if its being stirred, and are electroic refractometers accurate/reliable? Thanks.
