If you still dosing cackium now the difference between yesterday and today isn't testable , that's why we say dose on Alk number not calcium numbers the day to day testing for calcium can't be relied on as the testing noise is too wide . Alk isn't but if things stop growing (Rtn/stn)) your daily consumption of alkalinity slows thus the dosing amounts. Regarding the kalk added it's an Alk additive (ca too) so if there's nothing to consume it then it will stay the or will slowly drop as animals use it. The article say to use fixed amnts as the solutions are weighed that way , corals use Alk and cal at a fixed ratio of 1.4 dkh for every 10ppm of calcium for every 1ppm of mg An average system uses about 1 dkh a day so testing on calcium consumption can't be done on the same day ( you can't test a 10ppm drop) How much dkh a day is your system using ?
