I would not be to worried about all that. Over the last 14yrs. I have added it all. Never hurt a thing.
I have never worried about the top crust forming. The sediment in the bottom is best not to add. There are those, including myself, that drip the kalk still in its milky state.
One problem with that or using the sediment, is if non pure water is used in the mix, that kalks ability to precipate out phosphate from the water, builds up a phosphate accumulation in the sediment.
For newer users, I suggest either the valve be high enough, so as not to dose the sediment or after mixing, just dump the clear liquid in your doser.
It should be know though that kalk reactors continually mix the kalk up and dose as such.
