Fountains can act as surface aerators, though surface aeration is recommended only in the shallow areas of the pond as fountains are much less efficient than bottom-up aeration for increasing oxygen levels.

Fountains do have more visual appeal though than bottom up aerators and add to the decor of the pond! 

Essentially, the splashing of the fountain water traps oxygen in the top 6 inches to 16 inches of the surface pond water.

We include our aeration and decorative nozzles to increase the  

oxygen capture and depth that the surface aeration will go down. 

The deeper the splash the further down the oxygen penetration

goes which helps with the circulation flow in the pond.

Surface aeration also assists with minimising the amount of 

insect breeding in the pond by providing consistent surface agitation.
