Aqua Ultraviolet Ultima II Filters

This is the next generation of filters and the best tool for koi ponds. The Ultima II Pond Filter is specifically engineered to meet the environmental demands of ponds. The lightweight media is designed for very high flow rates.

There is a patent pending on this tubular pond filter media which has low head loss and a very high biofilm surface. The "Y" shape on the inside and wings on the outside affords a protective surface under backwashing which 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 pond filter media is equal to 750 square feet of surface area. 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.
