I need Help with Ca,KH,Mg

[MENTION=333331]homer1475[/MENTION] ^^^ see what I'm talking about with inconsistent RC measurements.. There is no way RC should be mixing up to what Phixman is stating..

RC should be in the 490ppm cal, 13 dkh, 1440ppm mag range..

It's hard to tell what boxes will read, not all are made with the same consistency, I've tested the bag many times and even mixed the bag. This was one of the reason I changed to Red Sea Pro, I'm fine with everything, but Mag. I've seen many users having issues with levels being too low, especially Mag.
