Aquascape Replacement Filter Pad Fits Grande Biofalls

No, this specific filter mat is engineered exclusively for the Aquascape Grande Biofalls unit. Its dimensions are 59" x 27" x 2", so it will not fit smaller or different Biofalls models properly.

Yes, the poly fiber material is designed to serve a dual purpose. It physically traps debris for mechanical filtration while providing a large surface area for beneficial bacteria to colonize, which handles the biological filtration.

Replacement frequency depends on your pond's specific bioload and fish population. Generally, you should replace it when the material begins to break down, loses its shape, or no longer effectively traps debris after cleaning.

While you can rinse the mat to remove trapped debris and extend its life between cleanings, the poly fiber material will eventually degrade. Once the pad loses its structural integrity or becomes too clogged to clean effectively, it should be replaced to maintain optimal water quality.

While the material can be cut, we do not recommend it. This mat is specifically sized for the Grande Biofalls, and altering the dimensions may compromise the fit, allowing water to bypass the filter media rather than passing through it.
