The components 1, 2, 3 are made for maintaining the levels not really for raising them up a lot.
It's always better to start slow and be conservative .
In the guide it suggests to start with 50ml per day of each per 27 gallons of water. This is a good starting point. My suggestion would be to get your big three levels set first. Before worrying about calcium and even alkalinity get your magnesium set around 1300 to 1400ppm. Then get your alkalinity and calcium balanced. I use this calculator to help.

Once your big three levels are set then your ready to start dosing the components 1,2,3. At the 50ml per day per 27gallons of water.
So let's say our tank is exactly 27gallons.
What your trying to do is to match your daily consumption.
So after your levels are set then you test.
Example
Calcium 420ppm
Alk 7.8dkh
Mag 1350 ppm
What you want to watch is the alkalinity. This is what you use to set all of your dosing levels.
Day 2 you test
Example
Calcium 415ppm
Alk 7.6 dkh
Mag 1350ppm
Ok so you see that in 24 hours your alkalinity dropped .2 dkh and your calcium went down a little also. The calcium will drop slower but don't worry about that for now. We are watching the alkalinity.
Day 3
Example
Calcium 415ppm
Alk 7.4dkh
Mag 1350ppm
Ah we dropped another.2dkh
So now we see that out consumption is .2dkh per day
Ok so now we know what we need to match. When we dose we need to match .2dkh per day of dosing.
So now we go ahead and get our levels back to where we want them or had them. Using that dosing calculator to help us.
Ok our levels are now back to day one levels.
Example same as day one
Calcium 420ppm
Alkalinity 7.8dkh
Magnesium 1350ppm
So in the guide it says that 50ml of component 2 raises alkalinity 1.3dkh some quick math tells us that 10ml will raise it .26dkh
So let's say you had a 27 gallon tank and you followed the guide and dosed 50ml per day of each component. You did the measurements above and you were still dropping 0.2dkh per day. Then you would need to increase your dosing to approximately 60ml per day . 50ml is the baseline and the 10ml increase due to consumption in order to keep your alkalinity stable at 7.8dkh.
Then you match that 60ml dosing of component +2
So components 1,2,and 3 are all now at 60ml per day.
Test test test. [emoji4]
Hope this makes sense. If I can help clarify anything just let me know.
