The Aquascape Signature Series BioFalls 1000 and 2500 are advanced biological pond filters designed to deliver crystal clear, healthy pond water using natural filtration processes. As part of the proven Aquascape ecosystem approach, these filters combine mechanical and biological filtration to create balanced, low-maintenance pond systems for garden ponds, koi ponds, and ornamental fish ponds.
Designed to integrate seamlessly into waterfalls and landscaping, the BioFalls filters provide both powerful filtration and a natural aesthetic, making them one of the most effective and visually appealing pond filtration solutions available.
The Aquascape BioFalls filter system works by mimicking natural aquatic ecosystems, using beneficial bacteria to break down waste and maintain water quality.
Water enters the filter through a dedicated inlet and passes through:
A swirl chamber that slows water flow and allows heavy debris to settle
A mechanical filter mat that captures fine particles
A biological filtration zone that supports beneficial bacteria growth
This process removes organic waste, excess nutrients, and suspended particles, helping maintain clear, oxygen-rich pond water.
For maximum biological filtration performance, Aquascape BioBalls filter media (sold separately) can be added above the filter mat. These significantly increase the surface area available for beneficial bacteria.
Each BioBall provides approximately 19 inches of surface area
Supports breakdown of ammonia, nitrites, and organic waste
