Strange maybe your initial test was off?
I have used lots of seachem products (mainly my old planted tank) but a few for SW and Their magnesium is the single only product I haven't liked.
My mg was low and over like 2 weeks I had dumped the entire 600 g tub in with no increase.
I got some mag. From little silver max and his product rasied it exactly what he said it would with an online calculator.
My guess is your original testing was off
