Aqua Ultraviolet ULTIMA II 4000 Filter, 1 1/2" Valve
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.

Note: Use Appropriate Pump For Filter Size (If you purchase a 4000 Gallon Filter, use a pump that will give you 4000 GPH at your Total Dynamic Head (10’ of pressure head plus vertical head height plus friction head (length and inside diameter size of hose with fittings such as elbows) for the best backwash. If you need help with this please contact us.
Additional Note: The Aqua Ultraviolet Filters should not be used with pipe dope inline as it will break down the valve of the Ultima Filter and will not be covered under warranty. Teflon tape is recommended.

Great Filter
Our pond has never been clearer since installing this filter. We had the same brand filter installed in our pond, but it was not working. Our pond was not staying clear for any time at all. When we checked how old the filter was we found that we had purchased it more that 20 years ago. It was also a smaller model that this one. We were able to install this one in just a few hours and it is doing a FANTASTIC job of keeping the water clear. We can see all the way to the bottom of the pond and see all our fish clearly now. It is such a pleasure to sit by our pond now. This is a great filter!
