The Aquascape Submersible Pond Filter provides efficient mechanical and biological filtration, keeping pond water clean, clear and healthy. This unobtrusive filter can be added to the intake of almost any submersible water pump, filtering ponds up to 800 gallons. The large surface area of the removable cage prevents large debris from clogging the filter and significantly decreases maintenance. The low-profile filter contains a pre-filtration sponge pack ideal for capturing smaller debris. The Aquascape Submersible Pond Filter also contains Ceramic filtration rings, providing substantial surface area for beneficial bacteria to colonize. The threaded intake and included multi-hose adapter ensures the filter is ready to adapt to most pond pumps with a small piece of pipe or ¾” threaded fitting. The Submersible Pond Filter also carries a 3-Year Limited Warranty. Aquascape is passionate about the products we produce, providing unique products, designs, and features that stand above the competition.
