Magnesium Low- help?

It seems like a lot and it scares me. I was dosing around 75ml every other day and my mag levels barely budged, so I must've way under-dosed previously

It always takes a lot to boost magnesium, but if you are using any normal brand of salt mix, the magnesium is almost certainly not 800 ppm.
