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?
