Blue Thumb Elite Cascade Falls Boxes Cascade Falls Boxes were created for Pond-Less applications instead of using a large bio-waterfall. Blue Thumb Cascade Falls Boxes include a black Matala mat which creates an even flow of water over the weir, a landscape lid for hiding the unit in the landscape, a detachable weir, and all the necessary installation hardware. Place them side-by-side for additional design options and waterfall widths.
