could my high precision hydrometer be wrong?
Yes.
I made some of Randy's DIY calibration fluid to verify mine.

could my high precision hydrometer be wrong?
Question out of curiosity:
Is there a formula or, better yet, calculator to determine overall salinity based on values of key major elements from an ICP test?
gotcha. my salinity is being read as 1.027 via icp?Yes.

well, dang. my corals and fish look fine, otherwise i didnt think they’d be able to tolerate extreme salinity like that !Higher then that. I just looked at the NACl you would have to add all the other ions also.
what a waste of time. at least it was only $8 per test. thanks for helping outI would toss the ICP results in the trash verify your hydrometer is correct and move on

Thanks,,, good to know.Simplest way if you have values for sulfate, chloride, calcium, magnesium and potassium is to just add them together. The total salinity will be just a bit higher than that.
Here we have
2.6 ppt sulfate (880 ppm x 3 = 2640 ppm , we need sulfate, not just sulfur)
23.4 ppt chloride (23,400 ppm)
12.3 ppt sodium
1.4 ppt magnesium
0.5 ppt potassium
0.5 ppt calcium
So from those alone we are over 40 ppt salinity.
Do they read high due to accuracy or is it inaccurately high?I personally would not trash the icp since they are ALL high
gotcha. i’m currently getting about 1.0265 on both my refractometer and TM hydrometerSimplest way if you have values for sulfate, chloride, calcium, magnesium and potassium is to just add them together. The total salinity will be just a bit higher than that.
