Question about diy calibration for salinity

[trainbob]

So my next attempt is to use the full volume in Randy’s article and pour it in a bucket and use a power head to mix it

Last post on this thread the volume method and using power head to mix solution was the winner. Calibration fluid measured 1.026 on the Milwaukee ma887 refractometer and 34 ppt on the aquarium solutions accuprobe swing arm

Curious, we don't use ordinary table salt in our home, we use coarser kosher salt.

Would that throw things off making the solution?

Hmm is it evaporated sea salt? That might not work the same as table salt.
If it's table salt but just larger crystals then you can just weigh it.

Go by mass, not volume, and it will be fine.

True, avoid sea salt for this purpose.

Thx x2, and its just kosher salt, though I do also have sea salt, and pink salt, and.... we're a foody couple :)
