It's normal. The direct intake will be different on every tank. On my 29 gallon I dose 12 mL of Alk, 10mL of Ca daily and have 2 tsp/gal of Kalk in my ato. Before I was dosing Kalk it was way different like as in 15 mL of Alk and about 20mL of Ca. daily.

The reasons for seemingly unmatched need are:

1. Delivery from pumps is not exact, so it may not be the same fluid per unit time (not a real demand difference)
2. Water changes with a mix not matching the tank in alk and/or calcium (not a real demand difference)
3. Not a perfectly matched two part (not a real demand difference)
4. Substantially rising or falling nitrate levels (not just steady) (This is a real demand difference)
5. Just not monitoring calcium long enough to properly determine demand since it moves up and down much more slowly than alk (not a demand difference)

Your experience may be related to any or all of these.
