Air pumps and winter
Do air pumps need to be housed 'indoors' when running during the winter months...or can I simply put it in a container to protect it from the elements...with the hose running to the pond? I just picked up an Optima pump and the directions appear to indicate that is needs to be in a climate controlled environment...but no verbiage stating that. Does anyone in zone 5 leave their pumps out all winter?
Any advice is greatly appreciated!!
