This filter media is used to help keep your pond clean and clear. Use this exclusively with Blue Thumb skimmers and waterfall boxes.

Biological Waterfall Boxes - Filter harmful waste and toxins from the water, keeping your pond clean and clear. Provides excellent surface area for beneficial bacterial growth while making a simple and artistic way of creating a waterfall. Easy to camouflage-especially when using our Landscape Lid that fits on our Elite Series. (Landscape lids are not available for DIY Waterfall Boxes.)

Black PVC Flex Hose - Carries water from skimmer box up to the biological waterfall box. Flex PVC is much easier to install than rigid PVC.

Rocks and Gravel - Are not included, but will be necessary for the complete installation of your pond. They provide additional surface area for beneficial bacteria to colonize, protects your liner from harmful UV rays and damage from animals. Plus they creates a beautiful, natural look.

Protective Underliner - A non-woven, protective underliner fabric forms a soft padding for the liner. Installs much quicker than newspaper and covers the vertical walls unlike sand. Unlike carpeting, it allows gases to escape out of the sides from the earth's soil.

Fish-Friendly Rubber Liner - Super-strong 45-mil EPDM liner is the best choice when building a pond. Very flexible - conforms to pond's curves and slopes.

High-Efficiency Pump - Pump sits in back pump chamber protected from clogging by nets and filter mats. Blue Thumb pumps are recommended as they will use far less electricity and are meant to operate continuously.

Mechanical Skimmer Box - Simplifies routine maintenance by removing floating debris before it sinks to the bottom of the pond. Protects the pump and hides unsightly plumbing.
