Let me just dispel that suspicion then ;-)
Alkaline Buffer does raise KH because it is bicarbonate based.
Acid Buffer will lower KH (and pH) because it is acidic (it is
bisulfate based, and actually says so right on the bottle ;-)
Since your KH is falling over the course of several days I suspect
your system is producing a lot of organic acids which are slowly
eating into your KH reserve. You could try increasing the amount of
chemical filtration to remove waste before it decays to yield acids.
Or just add a bit of Alkaline Buffer every few days or as needed.
Since your system is producing acids on its own, you don't need to
use the Acid Buffer when you're adding to the existing tank.
