You need to skim very wet to have this happen. It only happened to me
once (because I started kalkwasser), but my skimmer is in the sump, so
not really an issue.

If it hasn't generated skimmage yet, chances are it's not going to
overflow anytime soon. If it's a worry, just unplug it until you can
monitor it again.

Adjustment depends on your type of skimmer:

My ASM G3 has an outlet pipe that is the only adjustment. I could move
the outlet higher to skim wetter and I suppose reduce bubbles in the
outflow.

Some have an air jet that can be adjusted and if you have this, you can
adjust downward to reduce bubbles.

And, still others allow you to move the collection cup up or down to
adjust wet versus dry skimming. If you have this and are worried about
overflow, move your collection cup up.

Let us know what brand and model you have.
