All fountain units should be removed for the winter. If you use your pond for winter recreation then all aeration systems should be removed. Running the aerator in the winter is beneficial, however. The column of bubbles will keep a hole open in the ice, allowing for gas exchange during periods of heavy ice and snow. This circulation eases fish stress levels and also gives your bacteria a head start in the springtime. If you would like assistance with winter removal and unit maintenance, contact us regarding our Winter Storage Program.
