Kalk reactors, co2 reactors, etc.

couple of comments. Your pH is just fine and I wouldn't worry about it. Really small swing and the minimum is not too low at all.
Turbo calcium is CaCl. You will get a buildup over time of chloride in your tank from using it as a constant source. It is more designed to fix a problem once.
The kalk will only maintain levels, not change them. Again, determine what your consumption rates are so you know how much to add.
I find it strange that the alk stays at 11 dKh and the Ca jumps around so much.
