I had a problem a while back with my calcium and alk. My calcium, even though I don't add any, was always reading real high and I couldn't keep my alk up. I was given the advice of checking my magnesium. So now I got the Salifert test kit and my mag level is at about 2500. Is this too high? And can a high level of mag have caused my problem? I thought I would be looking for a low level. Also, I don't add any supplements except for occasionally upping my alk.
