Hi , I am using salifert test for mag, cal, dkh and phosphate. When doing my latest round of tests I noticed something on the Mag sheet that stated “calcium levels between 300-500ppm should not interfere with results”. My calcium tests at 540ppm. My mag has been testing off the chart 1500 plus. I even used a second syringe full and calculated that the mag was at 1600. My LFS API aqua spin test showed the mag was at 1280. I’m not so concerned with the actual number but more is the higher calcium skued the mag reading.
is there any way to “subtract” a value off of the mag reading if the calcium is above 500 ? Or is this not really a concern? I fell like mag at anyone of those levels is ok. I just wanna keep it stable and use a baseline number.
Thanks.
