This post is an update on my previous blog titled: Winter Survival of a KOI Pond Using an Air Pump (Figure 1). It is now February. A major snow storm dumped twelve inches of snow on the ice covered pond. Also, with the cold temperatures, the frozen water dome over the air bubble is completely frozen over. Meanwhile the air pump which is located in a dry location is humming away, pumping air into the pond. Although I can no longer see the KOI sitting on the bottom, my KOI are sitting on the bottom of the pond in darkness. They are still alive. In previous years, if a fish dies during winter, the dead fish would float and become encased as an orange blob in the surface ice. No orange blobs seem to be present, but then the snow covered ice makes it difficult to see.
