Looks like you are attempting to hit 1400ppm. Which is a little high.

230oz magnesium chloride hexahydrate would to the same.

You might want to do a mix.


If should have the same effect on salinity as a 10g ot 55g or whatever aquarium being as everything is in concentrations except for the actuall amount added.

IME very little if any effect will be noticed on your salinity.

As you already know the diy two part will still be required to maintain cal alk and magnesium. Water changes alone will limit but not prevent depletions or buildups of anything but it will limit them.
