The Aqua UV Ultima II External Filter is specifically engineered to meet the environmental demands of fish ponds
The lightweight media is designed for very high flow rates
Low head loss
Very high biofilm surface
This is the next generation of filters and the best tool for Koi ponds. The Aqua UV Ultima II External Filter is specifically engineered to meet the environmental demands of fish ponds. The lightweight media is designed for very high flow rates. The tubular Bio-Media has low head loss and a very high biofilm surface. The "Y" shape on the inside and wings on the outside afford a protective surface under backwashing, and with our patented 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. The Ultima II tubular bio-media offers the highest surface area for growth of beneficial bacteria. No other backwashable pressurized filter compares. Cleaning the filter is done by internal jets. The Ultima II is also the ideal filter for aquariums where very high flow rates are desired.
Aqua UV Ultima II 2000 Filter:
Dimensions (Diameter x Height): 16.5" x 33"
Pond Size: up to 2000 gal
Recommend pump flow rate: 2000GPH (at 10` of head pressure)
1 1/2" Inlet/Outlets (2" available upon special request)
Max Pressue 38 PSI
Top Valve Mount
Specifications
Ultima II systems are packed with ultra-high filtration bio-media that provides both mechanical and biological filtration, ideal for aquariums and fish ponds. The advantage of the Ultima II filter is it´s non-organic filter media with properties that encourage bacteria growth. The disadvantage of conventional bead filters is they have only a single-surface area which encourages a second layer of bacteria to grow over the initial layer. The enclapsulated bacteria underneath can become anaerobic. This continuous cycle can pose problems. Research led to three different types of media designed to grow and hold amonia-oxidizing bacteria and heterothropic bacteria. Just one cubic foot of these three media has over two million tiny shapes. One cubic foot of Ultima II Media is equal to 750 square feet of surface area. The Ultima II system is designed to offer you exceptionally clear water, great for ponds and aquariums. Cleaning is done by internal jet back-washing.

Notes:
Please use appropriate pump for filter size (i.e., if your pond is 2000 Gallons and you buy a 4000 Gallon Filter, use a 4000 GPH pump as well)

Before purchasing this filter I threw away $400 on a junk Chinese filter from a local vendor. With our 100+ degree temps and lots of sun we get plenty of algae. This filter was very easy to install and within 4 hours, my pond went from somewhat murky to very clear. The next morning it was sparkling and has been that way since. Very pleased with the filter.Hide

Aqua UV Ultima II 2000 Filter really performs as advertised! We've invested thousands of dollars on our koi pond with waterfalls and wanted to be sure we have the best filter installed; tech support such as "Robert" of MarineDepot.com was very helpful when asked for his professional opinion base on our koi pond size and needs; personal comments and reviews by previous buyers were also heavily relied on as the deciding factor in buying this product for our pond.

I have been using a gravity fed biological filter in my pond for the last 18 years; and, while it did the job, cleaning the filter box was a major disagreeable project. The prospect of having a back-washable filter enticed me into paying the high cost of this product. Was it worth it? I don't miss the cleanig chore, and it seems to be doing a good job. There's no magic here, but it seems to be as well designed as any of the other high end brands of pond equipment. I do shy away from the integrated UV. It is a popular trend to include UV sterilizers in other filteration equipment; which is fine as long as the replacement bulbs, starters, and balasts will be available for the life of the filter.Hide
