high magnesium in oceanpure pro

[ed99]

I've had high Mg levels from OPP as well. From batch C-09 I measured the following:

SG= 1.025 (refractometer)
Mg= 1800 (Salifert)
Ca= 500 (Elos)
Kh= 9 (Elos)
pH= 8.0 (Salifert)

Mg seems goofy-high, but the Mg level in the tank has risen past 1600 ppm. I'm struggling to maintain alk in the tank even though the new salt alk seem ok, so I'm not sure if the salt is the issue. I'll post that in a separate thread soon.

Looks like I'll be switching salts as well.
