The secret to maintenance-free ponds is in developing a healthy, balanced ecosystem that virtually takes care of itself. Pond fountains both beautify your body of water with an elegant display pattern and provide valuable oxygen and agitation to promote a healthy pond or lake.
Benericial bacteria growth sustains the biological filtration necessary to control the waste process in your pond. Anarobic (oxygen loving) bacteria literally eat and digest organic waste products, turning them into non-toxic nitrates and fertilizers for plants.
Adding water features such as pond fountains and water falls will add hours of interest, help discourage mosquitos, and help keep your pond healthy at the same time
Don't forget that if you want to add a water feature, purchase a pump larger than the one recommended for your pond size, as it takes more pressure to push a filter PLUS a fountain than a filter alone.
