Build an Above-Ground Waterfall
Place the preformed liner in the desired location and mark where the wall blocks should rest.
Place the base row of wall blocks 6 in. away from the bottom of the liner.
Install the lit waterfall spillway and waterfall pump. Be sure to follow the cascade's instruction manual carefully.
Fill the preformed liner with water to 2 in. below the top of the liner.
Plug in the cascade light and waterfall pump. Enjoy!
