Winterized skimmer and water entering

Hello,

Since the plastic top for the skimmer is not water tight, water will enter the skimmer cavity (rain/snow). This water will most likely freeze in the hole. Is this a problem? Should the hole have a couple inches of antifreeze added?

Please help.
Thanks!

I didn't find the right solution from the Internet.
