+1 on re-checking... and aim for around 1350+.
Also, there are powder kind and liquid kind. So following direction is recommended.
Mine say two time a week but I done like three times in a week before.
Magnesium dont rise too fast in my tank for some reason.

I'm guessing you mean 900 not 90...

What product are you using to dose it?
