My apex trident. Was showing some accurate results between that and my apex. However. As i approached 5% the results of mag, calcium started getting inaccurate. I looked it up and some people here said the reason for that its because im approaching low regabt. So i waited till the apex required me to change them so i did. And mag still 1200 instead kf closer to 1400 like salifert. Do i need to calibrate again?
