About Pond Pumps
A backyard pond filled with green, stagnant water probably is not the landscaping aesthetic you are aiming for. Pond pumps help keep water fresh, clear, and constantly circulating, and they provide the needed power for fountains, waterfalls, and other movement features. You must decide between an external pump that operates out of the water and a submersible pond pump placed at the deepest part of the water. Be sure to buy a pond pump filter that is compatible with the model you choose. eBay sellers offer new and used pond pumps from many major manufacturers.
