Recent Test shows high calcium and Magnesium

[jpbeen]

Just tested water with a Hanna tester for the following: Phosphate .12, Alk 7.5, Calcium 549 and nitrate 4.52. Salifert Magnesium test 1500. Is the calcium and magnesium too high? If so what should I do?

I wouldn't sweat the calcium and mag. They are on the high end, but not going to cause you any problems imho. You can slowly let it be consumed by corals or you can let it go down too when you do water changes.
