I consistently have high mag despite not dosing it. When I do dose which is rarely it’s aqua forest 3 part which has Mag separate from alk and calcium, my level are mostly replenished by water changes from Red Sea pro salt. For the most part I read my mag levels 1400+ according to Red Sea test and it was this way for a long time. Alk and calcium levels are good and I don’t have a hard time maintaining them, do you think the test is just inaccurate?
