I'd be surprised if it is actually that low. That would require very low salinity, or long use of a lot of calcium and alkalinity without any magnesium dosed.

How are you measuring it?

What salt mix are you using and what is the salinity?

That said, with any supplement it takes a HUGE amount of supplement to raise magnesium by hundreds of ppm.
