Does anyone else have problems with the waterfall going all the way across the teir when it goes into the pond? I have a pump that is well enough. And the top two teirs are good the waterfall covers the whole pice of flagstone. I always have a problems with this, so I move rocks around and then water flows where it wasnt then stops flowing in another section, I am irritated with this. I have checked it is level, I think it maybe the pump, even if i celan thebottom of the pump it doesnt seem to change theamount fo water flow, any suggestions? Should I cement the entire top waterfall so no water escapes underneath the rocks, and is forced down the falls, anyone have tricks up their sleeves?
