I purchased a pond breather for my first pond winter and it now has created an ice cone almost to the top of the tube. It’s working as I see water moving inside. I’ve seen other similar posts but nothing about how to fix - did I not put the top on correctly or is this just something that happens with all pond breathers in really cold climates like MN? My concern is this will continue to displace water from my pond beneath formed ice to top of ice
