The Aquascape Signature Series 6000 BioFalls® Filter with a 2" bulkhead is ideal for filtering ponds up to 6,000 gallons, providing efficient biological and mechanical filtration. Its durable, rotationally-molded, rounded polyethylene shape maximizes structural strength while making it easier to camouflage into your landscape. Able to handle flow rates up to 15,000 gallons per hour, the filter can be installed in a wide variety of applications. The Aquascape Signature Series 6000 BioFalls® Filter includes our patented non-cross-threading screws and reversible 28” waterfall spillway lip, providing the option of installing a natural stone spillway. The included rock and plant tray can hold rocks, plants, and gravel, helping to naturalize the BioFalls into the surrounding area. The filter is easy to install and comes complete with fish-safe silicone, hardware, dual 2” bulkheads, necessary fittings, media nets, and two Poly-Flo ESA biological filter mats that provide 50% more surface area than traditional filter mats. The filter also carries a limited lifetime warranty.
