Film on water surface due to Kalk?

Hi Randy,

I am using an autotop off to dose kalkwasser in my sump.
There is a milky white film on top of the water surface in the sump...do i need to be concerned?

Such a film will be reducing gas exchange a lot. A little turbulence in the sump might eliminate it. But by itself it is not a big concern.
