Currently have the Red Sea test kit for Calcium, Alk, and Magnesium and a Hanna checker as well for alk. I am consistently getting a magnesium of 1680 and a calcium of 540. The alk test on both the Hanna and Red Sea kit are the same at 7.8. Could the magnesium and calcium really be that high. Have tested multiple times over a couple weeks and get the same results.
