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
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.
