The Aquascape UltraKlean™ 3500 Pond Filtration Kit provides mechanical and biological filtration for ponds up to 3,500 gallons, taking the guesswork out of selecting the perfect combination of pond filtration equipment. Easily installed into new or existing ponds, the kit components are selected specifically for their compatibility, providing the best overall value for discriminating pond owners. The kit includes an UltraKlean™ 3500 Pond Filter with a 28-watt ultraviolet clarifier, self-cleaning function, and integrated electronic bulb-saver function. The unique sponge-free design of the filter minimizes maintenance, while the UV feature eliminates single-celled algae that cause green water. The kit also includes the AquaForce® 5200 Solids-Handling Pond Pump to provide the ideal flow for the filter. Also included are 25 feet of 1.5\" kink-free pipe, stainless steel hose clamps, and a 2-Way Flow Control Valve, which can be installed to maximize UV effectiveness. The UltraKlean™ 3500 Pond Filter and AquaForce® 5200 Solids-Handling Pond Pump carry a 3-year limited warranty.
