It absolutely does change alk, though it takes 24-36hrs before seeing the full potency of the dose. This is why afr needs dose calibration over a week or two.I dose kalk by alkalinity (when I used it basically replacing all evap with kalk) but AFR doesn't change alk the way kalk does (directly) which is why I dosed them differently
Dosing and testing to quickly can cause you to overshoot the desired level, but also allows higher stability since the drop will be slower.
