Did you test your mag? If your mag is low thats your problem . It need to be at 1400ppm If its lowere than that you will have a problem with alk and cal.

magnesium is always 1350-1400 no problem with mag

Double-check your mag test kit, then. With that level of magnesium you should have no problem getting above where you're at, and maintaining it.
