I am at the point where I want to automate my evaporation top up (and maybe even additive dosing). I have done some basic research and it seems that there are a couple ways to do it. First is to get a 'controller' like the one from JBJ or a Tunze Osmolator and use some third party pump or powerhead:

Could these systems be used with a kalk reservoir? Won't the pump burn out? In what increments do these systems work - would they add too much kalk at once?
The other alternative is to use a dosing system with a periastaltic pump like those from aqua-medic or liter meter

Obviously these are more expensive but would they be better?
Alternatively I could look into a kalk reactor but atm I need to use vinegar to maximize calcium addition and I am not sure if it is viable. Could I just spike the make up reservoir with some vinegar so that it runs through the stirrer? Lastly how reliable are kalk reactors/stirrers?
Thanks in advance.
