Does alkalinity affect skimmers?

I am not sure about total alkalinity but how you add alkalinity/calcium/kalk can. I was wondering why my sump heater and skimmer pump was covered with calcium deposits and it turns out it's because I was adding my three-part too quickly. I don't have a doser yet and do my additions manually every morning.

I've lost the thread which explained it but basically make sure each part and/or kalk is very thoroughly mixed into the tank water before adding in any other calcium/magnesium/alk supplement to prevent build up. The same article recommended putting the doser heads away from pump intakes and heaters and in an area of very high flow, such as the overflow drain into the sump.
