if you cut out the kalk but kept chloride the same as before the stn then your dosing less calcium as the kalk had calcium in it too so the chloride dose would need to be more to be the equivalent of both.
small differences in calcium are hard to control and test for ....it takes 1-2 weeks just to get an accurate consumption rate as the differences daily are to small.
sucks man every sps guys future and nightmare
