Why is my Magnesium so high?

[Hurgoth]

I ran a test tonight, something I have been slacking on the last few weeks. Here is what I found:

Calcium: 456
KH: 7.0
Alk: 2.51
Mg: 1470


How can I lower my mg?

MG between 1200-1400 is fine, your a little high but nothing to worry about IMO. This probably contributes to why you can maintain a high Ca level.

Mg should go down on its own...do you dose Mg?

Here's an articel you might find useful about water perms:

If you havent been dosing, then probably a faulty test.

Keep in mind even if you are not dosing a magnesium raising product usually products that raise calcium also raise Magnesium.

I wish I could keep mine that high. I dose all the time and I can't pass 1260.
