Could use some help dosing Seachem Magnesium

[Dw79]

I bought some Seachem Reef Advantage Magnesium today and was looking for some help with the amount. So the directions say 5 grams for 20 gallons mixed into at least 1 cup of water and not to exceed 25 grams for 20 gallons per day. If I'm reading this right, then for 40 gallons of water the max per day would be 50 grams mixed into at least 10 cups of water. Does this sound about right? Any help would be greatly appreciated

That would be the max amount at 25 grams.
Use your test kit to find out where you are now, add the least amount, wait 24 hours, then retest.

Perfect, thank you. Just wanted to make sure I don't over do it
