KH Director Set Up

Hello, I already received my KH Director but I do not know how to configure it. (I already read the manual and I do not understand. Sorry.) I handle the alkalinity of my aquarium at 8.5 dKH. I use a calcium reactor and I do a fine tune by dosing 7 ml of alkalinity (Tropic Marine Balling Part B ALK) in the morning, another 7 ml in the afternoon and, additionally, every day at night I measure the alkalinity with my Hanna Alk Checker and in order to raise my alkalinity, in case it is low, I must add 12 ml of balling alkalinity (Tropic Marine Balling Part B) to raise 0.5 dKH.
What work mode should I use with the KH Director: “Add-on Control Mode” or “Adaptive Control Mode” and how should I configure it?
Thanks.

As you know the exact amount you have to dose to raise KH, you should use add-on control mode.
In your case the volume change for 1 dKH is 24ml and on the limits you enter the maximum amount to change on the alkalinity dosing for raise and lower KH.
