Pond fountains add a therapeutic dimension to your pond with the soothing sounds of water. Pond fountains also improve the appearance of your pond - ideal for outdoor relaxation. What many are unaware of is that pond fountains provide economical benefits to your pond by aiding with aeration and circulation - ultimately resulting in better pond filtration and cleanliness. Pond fountains are most economically purchased in a filter/pump combination that will provide the proper water circulation and aeration and eliminating the need for a separate pump and filter. A small fountain costs between $120 and $200 online, while a large recreational fountain costs around $1,000.
