Aquascape Grande BioFalls Filter Mat

No, this mat is specifically engineered as a direct replacement for the Aquascape Classic Grande Biofalls unit (#09011). It is sized and shaped to fit that specific housing, so it may not function correctly in other filter systems.

The lifespan of the mat depends on your pond's biological load and debris levels. While it can be rinsed and reused several times, you should replace it once the fibers begin to break down or if it no longer regains its shape after cleaning.

While its primary purpose is mechanical filtration to trap physical debris, the poly-fiber material also provides surface area for beneficial bacteria to colonize. This makes it a dual-purpose component that supports both water clarity and biological health.

Yes, the poly-fiber material can be trimmed with heavy-duty shears if necessary. However, it is designed to fit the Classic Grande Biofalls precisely, so we recommend installing it as-is to ensure a tight seal that prevents water from bypassing the filter.

The most effective way to clean the mat is to rinse it thoroughly with a garden hose or a bucket of pond water. Avoid using chlorinated tap water or harsh soaps, as these can kill the beneficial bacteria living within the fibers.
