Aqua Ultraviolet Ultima II Pond Filters
The Aqua Ultraviolet Ultima II is a self-cleaning, multi-port-valve pond filter that has set the performance standard for pressurized pond filtration since 1999. The patented multi-port valve handles Filter / Backwash / Rinse / Recirculate / Closed positions with a single key-handle turn — making routine media cleaning as easy as cycling the valve and letting the dirty water exit through the waste line. Available in 1,000 / 2,000 / 4,000 / 6,000 / 10,000 / 20,000 / 30,000 / 60,000 gallon-class sizes with 1-1/2", 2", or 3" Side Mount Port options. Built in Temecula, California with a 5-year warranty on the filter body.
