Aqua Ultima II 10000 Filter - 2"

The Aqua Ultravioliet Ultima II Filter is available in four standard models suitable for ponds from 1,000 to 20,000 gallons capacity. Aqua Ultraviolet claims that its biological filters take only minutes to backwash and can handle heavy fish and feed loads. Equipped with ‘cyclonic’ back washing, Ultima II features Bio-Tube aqua media. These media are of tubular design, which aims to protect bacteria while dislodging unwanted debris. And is lightweight designed for very high flow rates.

 

The ‘Y’ shape and the inside wings on the outside affords a protective surface under the back washing and the company’s patent-pending backwash system will keep the media from clogging. The same properties have been added to this media in three different sizes with random lengths and diameters to avoid stacking, one cubic foot of Ultima II media is equal to 750 sq ft. of surface area. Cleaning the filter is done by internal jets. The Ultima II filter, tested and used my MIT (Massachusetts Institute of Technology) has outperformed the competition, according to Aqua Ultraviolet. Tested side-by-side against all bead filters on the market the Ultima II filters have been found to be "by far, the best," claims the company.

The Ultima II, which is seeded with bacteria, works like a centrifuge. The valve being rotated to backwash will set the filter into cyclonic motion. A valve located inside the filter closes, which then diverts the water through the jets sending the media spinning out to the walls of the filter, while dislodging the waste, causes it to separate and be sent out through the waste outlet.

The Ultima II will work with any pump appropriate for the pond in question. The Ultima II’s bio media with it’s patent pending design is light enough so that the water from the pond will completely and quickly backwash the filter. Filters can be buried up to the valve top.
