Maximum flow: 10,000 GPH
Pond capacity: Up to 6,000 gal.
Inlets: Two 3-inch spinwelds

Built for High-Flow Pond Waterfalls

Filtration and Waterfall in One

Water enters through the lower plumbing connection, moves through the filter media and returns to the pond across the detachable 30-inch spillway.

Flexible Plumbing Layout

Two side spinweld fittings let you bring the feed line in from either direction. The second fitting can be plugged, used for a second pump line or configured for back-flushing.

Easier to Conceal

The faceted box profile and included landscape lid help integrate the filter into a berm, stream head or pond edge while preserving access for maintenance.

What Comes with the Waterfall Box

The supplied parts support installation of the box and its liner connection. The biological media that fills the mesh bag is selected separately.

Compare Waterfall Box Sizes

Choose the model around the pond volume, planned waterfall width and actual pump flow at the installed head height. Maximum flow is a box limit, not a promise that every pump will produce that flow after plumbing and elevation losses.

Installation at a Glance

Review the complete installation guide before excavation or liner cutting. This built-in component must be supported, leveled, plumbed and sealed correctly.

Choose the Location

Place the waterfall opposite the skimmer for pond circulation, either at the pond edge or at the head of a stream. Confirm viewing angles and access for future media cleaning.

Prepare and Position

Compact the support area to reduce settling. Keep the box level from side to side and tilt it slightly forward—about one-quarter bubble—so water travels evenly toward the spillway.

Connect the Plumbing

Choose the inlet side, tape the threaded male adapter and plug the unused fitting unless it will serve a second pump line or back-flush setup. Join clean flexible PVC with the appropriate PVC primer and cement.

Attach Liner and Weir

Leave a little liner slack, clean the bonding surfaces, apply the included silicone, fasten the weir with the stainless screws and only then trim the liner opening. Follow the manual’s fastening sequence.

Load the Filter Media

Set the two Matala mats horizontally in the bottom. Fill the mesh bag with selected biological media and place it above the mats.

Finish and Test

Install the landscape lid, complete the rockwork and use black waterfall foam where needed to direct visible flow. Test for even spillway flow and leaks before final landscaping.

Care and Seasonal Maintenance

Protect the Bacteria Colony

Inspect the system as pond conditions change. When the waterfall media needs cleaning, rinse it with pond water when possible; chlorinated tap water can damage the beneficial bacteria.

Clean at the Right Time

The installation guide calls for a thorough waterfall-media cleaning about once per year, when water is coldest or below 50°F. Actual maintenance frequency varies with debris, fish load and feeding.

Prepare for Freezing Weather

In climates with prolonged freezing, remove the pond pump and follow its storage instructions. Rinse and store the removable media for winter, then reinstall it during spring startup.

Frequently Asked Questions

Is this a complete pond kit?

No. PB1090 is the biological waterfall box and its listed installation hardware. The pump, skimmer, flexible PVC, liner, underlayment, loose biological media, primer and cement, waterfall foam, rocks and gravel, electrical service and site work are selected separately.

What pump flow can the Large Elite Waterfall Box handle?

The maximum recommended flow is 10,000 GPH. Size the pump by its delivered flow at your installation’s total dynamic head—not by the pump’s zero-head rating—and stay within the waterfall box limit.

What size pond can it filter?

It is rated for ponds up to 6,000 gallons. Fish load, feeding, debris, sunlight, circulation and maintenance also affect filtration needs, so contact our Sales/Tech Team when the pond will carry a heavy biological load.

Can I use 2-inch or 3-inch flexible PVC?

Yes. The installation guide states that the 30-inch Elite Waterfall accepts either 2- or 3-inch flexible PVC. The box has two 3-inch spinweld fittings; use the supplied plumbing adapter arrangement and confirm the complete plumbing plan before installation.

Is biological filter media included?

Two green Matala filter mats and one mesh media bag are included. Loose biological media for the bag is not included. Our sizing guidance recommends 5 cubic feet of Bacti-Twist for the 30-inch box.

Where should the waterfall box be placed?

Place it opposite the skimmer to encourage circulation through the pond. It may sit at the pond edge or at the top of a stream. Compact the base, keep the box level from side to side and maintain access for media service.

How often should the waterfall media be cleaned?

Inspect it according to pond conditions. The guide recommends a thorough cleaning about once per year when the water is coldest or below 50°F. Rinse with pond water when possible so chlorine does not harm the beneficial bacteria.

What warranty applies to the waterfall box?

Blue Thumb’s lifetime limited plastics warranty covers Blue Thumb-branded engineered-plastic waterfall filters against manufacturing defects for the original purchaser, subject to proper installation and the complete written terms. The warranty does not extend a lifetime term to separately purchased pumps, lights or other equipment.
