Trident accuracy!?

[zheka757]

Got trident, second week ok testing!
Got to say, I'm very impressed with how accurate alk and calsium is.
Comparing alk with Hanna checker. Is .1-.2 dkh difference
Comparing calsium, with red sea. Less then 10 ppm difference.
I mean can't complain with above reading. Pretty much spot on every time.
Problem I got is magnesium.
I'm checking red sea, and I'm getting 1200 every time. But trident shows 1340!? I want to trust trident. But not to sure. Need to compare with another test kit.
How accurate is your magnesium on trident?

I do find occasional false readings and will repeat test and get a result closer to hanna test results.
