Waterfall filters and weirs simplify the process of building waterfalls by creating a wide sheet of water flowing across a level plastic surface. Spray foam is used to bed one or more wide flat rocks over the surface, concealing the plastic and forcing the water to flow over the rocks to start the waterfall.
WATERFALL FILTERS: A waterfall filter is a molded plastic tank filled with filter media that serves both as a pond filter and as the headwaters for a waterfall. This tank is normally dug into a hillside above the pond and carefully concealed with rocks and plants so that it becomes invisible. If the site has no hills, it can be set onto flat ground and soil from the pond excavation can be used to create a hillside around it. Although vortex filters, pressure filters, and gravel filters are preferable for koi ponds, waterfall filters offer inexpensive and low-maintenance filtration for typical landscape water features with low biological loads.
Elite Waterfall Filter
Elite Waterfall Filters are made of thick rotational-molded black polyethylene and use a detachable lip that makes it easy to attach rubber liners to the tank. Water is pumped into a settling chamber at the bottom of the filter through one of the two fittings provided; the other can be used for backwashing. From there it flows upward through two layers of thick plastic filter matting (Matala) and through several inches of filter rock until it reaches the lip at the top of the filter and spills out to begin the waterfall. We offer four sizes: small (14" spillway, 2500 GPH maximum, 25" x 19" x 23" tall), standard (22" spillway, 5000 GPH maximum, 31" x 26" x 23" tall), large (30" spillway, 7500 GPH maximum, 41" x 26" x 27" tall), and extra-large (40" spillway, 10,000 GPH maximum, 48" x 33" x 31"). The nylon mesh filter bag supplied with the filters can be filled with our super-efficient ceramic filter rock, with locally available lava rock, or with plastic bioballs. These filters are supplied with a unique lid designed to be filled with rocks, soil, and plants for concealment while allowing access to the filter media without the need to remove the lid.
Livingponds Waterfall Filters are made of injection molded black polyethylene and also use a detachable lip for easy liner attachment. Water is pumped into a chamber at the top of the back of the filter from where it flows down to a settling chamber at the front of the filter and upward through a ribbon filter media (Springflow) and a layer of polyester matting until it reaches the lip at the top of the filter and spills out to begin the waterfall. A backwash fitting is provided at the bottom.
WATERFALL WEIRS: Waterfall weirs differ from waterfall filters in that their primary purpose is to serve as the headwaters for a waterfall while providing little or no filtration. They may be dug into a hillside above the pond or installed within the pond: in either case they are carefully concealed with rocks and plants so they become invisible.
Cascading Falls are truncated versions of the Elite Waterfall Filters and feature the same sturdy construction and plastic filter matting. They are also supplied with a similar lid designed to be filled with rocks, soil, and plants for concealment while allowing access to the filter media within. We offer five sizes: mini (10" spillway, 1500 GPH maximum, 10"x8"x8" tall), small (14" spillway, 2500 GPH maximum, 24" x 15" x 15" tall), standard (22" spillway, 5000 GPH maximum, 34" x 16" x 14" tall), large (30" spillway, 7500 GPH maximum, 41" x 16" x 16" tall), and extra-large (40" spillway, 10,000 GPH maximum, 52"x16"x16"). All except the mini size have 2" threaded ports at either end.
Filter Weirs are made of injection molded black polyethylene and use a clamping plate for liner attachment. In spite of their name, they have very little filter media capacity. However, they are well made and provide an inexpensive means to start a waterfall. We offer two sizes: one with a 16" spillway (2500 GPH maximum, 18" x 10" x 11" tall) and one with a 31" spillway (7500 GPH maximum, 33" x 12" x 10" tall).
