What is the difference between a pond fountain and an aerating fountain?
A pond fountain and a decorative aerator are both floating units that float on the surface of the pond or lake but are anchored out there with cement blocks so that it is stationary. A pond fountain is a decorative floating unit that uses a high volume waterfall pump with an impeller. Generally the spray heights are higher than an aerator and this type of fountain is less expensive than an aerator. Although these units will aerate your pond, it moves less water than an aerating fountain.
A decorative display aerator is also a floating unit that uses a motor with a propeller. It moves a large volume of water compared to a fountain. It can handle dirty water environments, introduces a lot of oxygen into the water and retards the grow of algae and weeds. Great for lakes or pond with fish and algae problems.
