I originally posted this general post but now it has changed to more of a chemistry post, I think. If you need I can copy and paste my previous posts on this problem?

I read somewhere that you can take your measurements after the salt has totally dissolved? I’m waiting at least 2 hours after salt has totally dissolved, just to be sure.

Measuring salinity with ATC refractometer. My test equipment is:
Hanna for Alkalinity - Phosphate - Calcium
Red Sea for Magnesium Pro
What test equipment should I use for Potassium?

Different salt mixes take different amounts of time to mix. I'd check the directions on the box

I always let mine mix over night now. I use coral pro. If I measure 2 hours after and again the next morning I get 2 different readings.

If the water is clear, and nothing is precipitating out, the only things that can change with more mixing are gases such as O2, N2, helium, CO2, etc., and pH and ORP, since they are impacted by gas exchange,

Changes in things like calcium, alkalinity, and magnesium are either test error, or the result of incomplete dissolution and/or precipitation.

I was only referring to my salinity. Coral pro takes a little bit to clear up. I know better than to argue with you.
