I have a JBJ 28 running for almost a year and so far I have not had to dose calcium because it constantly stays at 440-460 depending on the size of my water change. Alkalinity on the other hand I need to dose approx. 8ml a day of B ionic alkalinity to keep it in check. Is this normal for a tank that has mainly LPS? Shouldn’t my calcium be getting used up more as well?
