If you look online in the right places, you will find the answers to these basic questions because I have published articles answering all of them.

Do you know what your pH is now?

That test does not suggest any changes are needed. Great reef tanks can have pH between 7.8 and 8.6.

If you are trying to optimize the calcification rate of SPS corals, higher in thst range is better. You are not in that situation and should not, at this point, focus your husbandry efforts on raising pH. If you do it with additives, you will likely end up with excessively high alkalinity.

Test dose calcium, alkalinity, magnesium dose
wait 20 minutes test.

4 days test, divide 4 see mls needed if needed to dose for calcium, alkalinity, magnesium.

Dose mls for calcium, alkalinity, magnesium.

Test ph dose kalkwasser the mls on calculator test every day see what + ph when you get to 8.1-8.3 see what the mls.

Test 3 days, 1 week. ph - you know what is needed for dosing.

Dosing kalkwasser is + calcium 3.37 ppm a day alkalinity 0.47 dkh a day.

I think you are not getting good advice.

I strongly recommend you do not follow any plan that has you dose kalkwasser to attain a specific pH rise because alkalinity will very likely get too high.

What is the alkalinity right now? I have not seen any discussion of whether you need alkalinity, and kalkwasser should not ever be dosed if you do not need alkalinity.

Alkalinity is the very first and by far the most important thing for you to know in a new tank. pH correcting is far down the list.
