There are several different trees and bushes surrounding our pond. As fall season peaks, the amount of leaves and needles falling into the pond gets quite high. There are koi, sturgeon and goldfish living in the pond.
We have a skimmer to clean the surface water, though floating material always accumulates in some corners of the pond. There is no guarantee the skimmer is cleaned as regularly as it is during fall. Another access point for the pump is at the lowest spot of the pond, to keep the base of the pond free of dirt.
My main concern is that a net makes the pond look far uglier than uncollected/un-skimmed floating material. Given these conditions, is there any reason to cover the pond with a net during fall season?
