I'm not trying to hijack your thread but I have a kh/ca/ph question and maybe an answer to mine and yours will help one another. Simply I thought a proper ph is balanced by a normal ca and kh. I have a reef tank so I am trying to get my ca up. My kh is 8, ca is 390 and ph is 7.97. I need to get the ph up or get a new tester to make sure mine is testing right. I've been dosing with seachems calcium for about a week or so and it has moved my ca up and kh down and my ph up. Do I keep adding the calcium until my kh gets border line and then start adding alkalinity and go back and forth until I get them both in the right range? Would that stabalize my ph also? I have not used any ph buffer and my ammonia, trates, trites, phates, temps, ... have tested normal.

If you add the calcium slower then you will have less kh drop. So I raise the kH to 10-12 first then the calcium. If I am not adding much calcium then I don’t add as much to the kH.

No buffer that I have used will account for all rates of loss of all the buffering minerals so the real answer is no but you can find that one buffer will raise alk and the other help move pH and this type of switching from one buffer to another can help keep pH where you want.
