SKU: A50073-Grouped Categories: ,


Aqua Ultima II Pond Filters were designed with the garden pond enthusiast in mind! The unique patented biomedia was developed from poor performance of bead filters. The media in bead filters typically “clumps” together and has to have air blown into it to un-clump the media. Bead filters also lose performance once they become dirty.

The Aqua Ultima II does not experience any of the problems typical to bead filters. Tubular media filters the garden pond and will last many years. There are actually six different sizes of media within every Aqua Ultima II filter. The unique design of the media prevents the media from clumping and/or channeling. The water has to go through all the media, thus creating a clean healthy garden pond. Look below the specifications table for more info on the biomedia used in Aqua Ultima II filters.

Aqua Ultima “Tubular” media:
Ultima II systems are packed with ultra-high filtration bio-media that provides both mechanical and biological filtration, ideal for Fish and Koi Ponds.
The advantage of the Ultima II filter is its non-organic filter media with properties that encourage beneficial bacteria growth, while the disadvantage of conventional bead filters is the single-surface area of the media which encourages a second layer of bacteria to grow over the initial layer. The encapsulated bacteria underneath can become anaerobic. This continuous cycle can pose problems.
Research led to three different types of media designed to grow and hold ammonia-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 Garden and Koi Ponds!
Cleaning is done by internal jet back-washing.
