calcium/mg test kit

[jaynigz]

what's a reliable test kit for these guys? any one with a particular brand that they trust?

Salifert seems to be good for calcium. I have found this test to show false low values on Mg. I use ELOS test kit for Mg. It seems to be more accurate over a longer period of time. Hope this helps.

Red Sea Pro very reliable and cheaper than Salifert or Elos for either

You can get all three Ca, Mg and alk in a kit from Red Sea Pro. It's about $50, and the refills are dirt cheap.

I just got the Red Sea Pro as well. Getting along with it quite nicely.

I used Salifert for magnesium, and it seemed okay. I have used IO and Salifert for calcium, and they gave similar results, although the IO test was quite a bit slower to run.
