Ultima II 1000 Filter 2"

Aqua Ultraviolet Ultima II is a compact biological and mechanical pressurized filter that removes debris and nitrifies any ammonia in your pond making it a better environment for your fish. The Ultima II pond filters are ideal for ponds ranging from 500 to 30,000 gallons, especially those with extreme fish loads and/or elevated feed rates. We recommend operating the filter with an in-line direct drive or centrifugal pump for optimal performance.
