Pond aeration and fountain systems are important because they help keep ponds healthy by mixing air (i.e. oxygen) into water. Most pond and lake owners have a very specific vision in regards to what they want, whether a clear, cool swimming hole, a wild and woodsy nature attractor, or something in between. While some ponds are naturally aerated, others need a little outside help. This is where a pond and fountain aeration system comes in handy!
