Aquascape Signature Series BioFalls 6000 Waterfall Filter

Aquascape Signature Series BioFalls 6000 – Waterfall Filter (2” & 3” Inlet) for Large Koi and Garden Ponds

The Aquascape Signature Series BioFalls 6000 is a high-capacity waterfall pond filter designed for large garden ponds, koi ponds, and professional pond installations. Engineered to deliver powerful biological and mechanical filtration, this advanced system helps maintain crystal clear water, improved oxygen levels, and a healthy aquatic environment.

Available in both dual 2-inch inlet and dual 3-inch inlet configurations, the BioFalls 6000 is ideal for high-flow pond systems and larger water features where performance and reliability are essential.

Advanced Biological Pond Filtration

The BioFalls 6000 is designed to maximise biological filtration efficiency, supporting beneficial bacteria that break down ammonia, nitrites, and organic waste.

The filtration process includes:

• A swirl chamber that slows water flow and allows heavy debris to settle

• Dual Poly-Flo ESA filter mats with increased surface area for bacterial colonisation

• Optional BioBalls filter media to significantly expand biological filtration capacity

This combination delivers effective pond water treatment, waste breakdown, and nutrient control, helping to maintain balanced pond conditions.

Designed for Large Ponds and High Flow Systems

The BioFalls 6000 is built for demanding pond environments:

• Suitable for ponds up to 22,700 litres (6,000 gallons)

• Maximum flow rate up to 56,800 litres per hour

• Wide 71 cm spillway for strong water return and enhanced oxygenation

This makes it an ideal solution for koi ponds, heavily stocked ponds, and large ornamental water features.
