Does it detect Magnesium and Calcium

Yes. It detects TOTAL hardness which includes magnesium and calcium combined. It will not tell you how much of each is present, just the total amount. Thank you!

How can I get the latest expiration date possible from the Water Works inventory?

Good afternoon. Our current inventory (as of February 7, 2017) has expiration date of 5/2018.

Does it have a color guide on the bottle?

Yes. The bottle has color chart on the side. Detection Range in Parts per Million: 0, 40, 80, 120, 180, 250, 425, 1000 ppm (mg/L). Detection Range in Grains per Gallon: 0, 2, 5, 7, 11, 15, 25, 58 gpg. And finally, this product detects total hardness, meaning it will pick up both dissolved calcium and dissolved magnesium. It will not, however, tell you which of the two it detects.
