I am looking for a way to help calm the water coming from the waterfall so I can see into the pond better. I don't want to take apart the large slab that the water runs over as it would be difficult to anchor again now that the pond is running. I was thinking maybe a curved 1/4" clear plexiglass in front of the waterfall just at water level. Other choice might be to try and raise the water level but not sure that would help or that I have the liner height.
