The time has come to kick in the aerator. Light snow cover and lots of cloudy days. I kicked it on this morning and I can see it has started opening a hole at the shore. Interesting that sometimes the hole opens first above the diffuser and sometimes it opens at the shore. I don't know for sure, but I think the hole appears first at the shore when the water level has dropped a bit under the ice.
