Had me scratching my head for a couple days on this one but I figured it out.
When you enter your aquarium volume in gallons, the calculation uses liters instead giving a result that is off by the 3.79 liters to gallons conversion factor. When you enter your aquarium volume using Liters, the calculation is still off by 3.79x.
To get the correct calculations for now, till they fix it, select gallons as the unit, but enter the tank volume in liters instead.
I have posted about this error in the Fertilator feedback thread.
