BioFalls® Filters
Aquascape BioFalls® provide biological filtration and help create a beautiful, low-maintenance water garden.

Understanding Biological Pond Filtration
BioFalls® Filters
Biological filters are positioned to create the beginning of the waterfall in your pond. The filter uses bacteria to break down pond wastes, converting them into less harmful compounds that can be used as aquatic plant fertilizers. Water enters the biological filter from the skimmer via flexible pipe located near the base of the unit. The water then flows from the bottom to the top of the filter, traveling through filter media housed inside the unit. The filter media helps with the removal of fine to medium-sized particles.
As the biological filter fills, it overflows and cascades over its waterfall lip, cascading down rocks that have been set to create a beautiful, natural-looking waterfall. The waterfall creates aeration for your pond, assisting in the circulation and health of the water. Aquascape BioFalls® Filters range in size and can filter ponds up to 10,000 gallons. For larger ponds, multiple biological filters can be incorporated into the design.
