The foam in my skimmer isn't condensing into the collection cup. It's
creeping out the vents and running down the side. I started replacing
evaporate with kalkwasser about 2 weeks ago w/ a drip line.

Sounds nasty, but unfortunatelly cannot help - did not happen to me.
Are you sure the skimmer is cleaned and there is no obstacle on
the way for the foam to collect properly ?
