I use API and Salifert.

The API Calcium is IMO a very good test. I use it the 3 of 4 weeks a month. The 4th I use the Salifert Stronium test which has the Calcium test in it.

The API kH test is good, I have used it, but it give you whole numbers only (8,9, etc), The Salifert is more detailed (8.1, 8.2, 8.3,...).

Mag its Red Sea or Salifert. I have not used the Red Sea but from reading the reviews it is not as detailed as the Salifert.

I use a small milwaukee handheld for my ph. You have to calibrate it a few times when you first buy it, but after that it works well.

I use API for my CA and Alk. I water change every week, so I don't test for Mg.... yet
