Filters While It Builds the Waterfall
Water rises through the media from below, helping capture suspended material and providing surface area for beneficial bacteria before it returns to the pond over the spillway.

Aquascape Signature Series 6000 BioFalls® Filter with 3" Bulkheads

Aquascape Signature Series 6000 BioFalls® Filter with Dual 3-Inch Bulkheads
Build the head of a substantial pond waterfall while adding mechanical and biological filtration for ponds up to 6,000 gallons. This exact #29384 configuration combines a wide 28-inch spillway, dual 3-inch plumbing ports and a rounded, rotationally molded polyethylene body designed for high-flow pond systems.

15,000 GPH Maximum pump flow
28 in. Waterfall spillway
Dual 3 in. Bulkhead ports
Why Choose the 6000 BioFalls?
Made for High-Flow Designs
The dual 3-inch bulkheads accept the included 3-inch PVC slip fittings and give installers flexible plumbing options for systems flowing up to 15,000 GPH.
Designed to Disappear
The rounded body is easier to blend into a waterfall berm, while the included rock-and-plant tray supports small boulders, gravel and aquatic plants used to conceal the top.
Before You Order: This Is a Filter, Not a Complete Pond Kit
The pump, skimmer or other prefilter, liner, plumbing pipe, BioBalls, stone, gravel, plants and installation labor are sold separately. This model is 40 inches long by 45 inches wide by 29.5 inches high, so plan room for the filter body, plumbing, waterfall berm, backfill and future service access.
Silicone packing note: Aquascape's current product page lists fish-safe silicone as included, but the official installation manual says silicone is not included. To avoid an installation delay, we recommend having compatible fish-safe silicone available.

View the Blue Thumb Large 30 in. Elite Waterfall BoxWhich One Fits Your Project?
Choose the Aquascape Signature Series 6000 when the design calls for flow above 10,000 GPH, a rock-and-plant tray, or coordination with an Aquascape ecosystem-pond layout. Choose the Blue Thumb PB1090 when you prefer a slightly wider 30-inch spillway, a smaller overall filter footprint, included Matala media and a landscape lid. Confirm total dynamic head, desired waterfall appearance and downstream plumbing before selecting a pump.
Plan the Installation
Choose the Waterfall Location
Place the BioFalls near the pond edge and orient the spillway toward the main viewing area. When paired with a skimmer, Aquascape recommends placing the BioFalls across the pond from it to support circulation.
Set, Plumb & Level
Install the two reverse-threaded bulkheads with the rubber gaskets inside the filter. Set the body at or slightly below grade on firm ground, connect the plumbing, then recheck level before compacting backfill.
Attach the Liner & Lip
The reversible lip can face outward for a straightforward ledge or inward for more freedom when placing large waterfall stones. Clean and dry the sealing surfaces, use fish-safe silicone, and allow at least one hour of cure time before adding water.
Load the Filter Media
Place the two mats on the support rack. Fill the included media nets with separately purchased biological media without overfilling them; Aquascape recommends 400 BioBalls for this model.
Build & Test the Waterfall
Frame the spillway with boulders, direct water over the desired stones with pond-and-waterfall foam, and run the system before trimming excess liner. Premature trimming can create avoidable leaks.
Conceal with Service Access
Use the rock tray for gravel, small boulders and aquatic plants, but keep the front opening accessible so the mats can be removed during annual maintenance.
Existing-Pond Installation
The Aquascape manual calls for an additional liner piece approximately 4 feet by 6 feet when adding the BioFalls to an existing pond. The liner must reach the spillway and overlap the pond edge with enough material to prevent water loss.
Maintenance, Seasonal Care & Safety
- When used with a Signature Series Skimmer or Pondless® Waterfall Vault prefilter, Aquascape designs the BioFalls for approximately once-a-year cleaning.
- Do not clean the mats or biological media more than once a year, and avoid chlorinated tap water; overly frequent or chlorinated cleaning can reduce beneficial-bacteria populations.
- Replace filter mats after several years when they begin to tear or fall apart.
- An optional BioFalls drain kit (#29015) can simplify water changes and annual cleaning.
- Drain and winterize connected plumbing, pumps and check valves as required for your climate. Improper winterization can void applicable warranty coverage.

Frequently Asked Questions
Is this the 2-inch or 3-inch BioFalls model?
This page is for Aquascape item #29384 with two 3-inch bulkhead ports and two included 3-inch PVC slip fittings. The 2-inch version is a different configuration, item #29319.
Is a pump included?
No. The pump, skimmer or other prefilter, pipe and check valve are sold separately. Select the pump from the waterfall design's required flow after accounting for total dynamic head; do not exceed the BioFalls maximum rating of 15,000 GPH.
Are BioBalls included?
No. Three filter-media nets are included, but biological media is sold separately. Aquascape recommends 400 BioBalls for the Signature Series 6000.
Can the filter be added to an existing pond?
Yes. Plan for plumbing from the pond or prefilter to the BioFalls and an additional liner piece approximately 4 feet by 6 feet to connect the waterfall spillway back to the pond. Site conditions may require a larger liner section.
Can I use a natural stone spillway?
Yes. The reversible lip supports multiple waterfall-building approaches. For an outward-facing lip, the manual permits a piece of natural slate no more than 3/4 inch thick, secured and directed with pond-and-waterfall foam.
How often should the filter be cleaned?
Aquascape designs it for approximately annual cleaning when a Signature Series Skimmer or Pondless® Waterfall Vault prefilters large debris. Do not clean the mats or media more than once a year, especially with chlorinated tap water.
What warranty applies?
The BioFalls filter carries a limited lifetime warranty against manufacturing defects when properly installed and maintained. Plastic internal parts carry one-year coverage. Filter pads and media are consumable and not covered; proof of purchase and other exclusions apply.
