Product Features
Product Reviews
The Ultima II does the work of two filters combining both biological and mechanical filtration into one compact package. The Ultima II filter uses a tubular patented media with a very high surface area; this exceptional design feature protects beneficial bacteria during backwash and prevents clumping. The Ultima II filter is preseeded with bacteria, which helps to jump start the filter's growth of beneficial bacteria. Simply by rotating the valve the patented cyclonic backwash system does the dirty work for you. In just minutes the internal jets clean the filter for you.

Independent laboratory and Field testing has shown the Ultima II out performs all other filters on the market.

    What makes the Ultima II Filter Different?

    How is the Ultima II Filter different than a bead filters?

    Bead filters use raw pellets
    Bead filter manufactures just take these inexpensive pellets and load them into a filter body as is. The wax based plastic and smooth shape encourages clumping which is an inherent problem in bead filters. Some bead filter owners have been forced to backwash every day to prevent this clumping.  When the beads stick together, water and waste pass around the large mass making much of the beads surface inaccessible. This allows untreated ammonia and solids to pass right through and return to the pond.

    Ultima Media is specifically designed to support aquatic life
    Using non wax based plastic Aqua Ultraviolet extrudes a patented media with the highest surface area of any on the market. The small tubular design has ridges on the outside and a cross section on the inside increasing bio surface area and preventing clumping. The ridged design helps to create a dense bed for superior trapping of solids that is easily separated during the backwash.

    How can the  Ultima II filters be smaller than bead filters and handle more fish
    The Ultima II patented media design has 800 cubic feet of surface area per square foot. This is the highest surface area of any product on the market. The high surface area means less volume of media is needed so the filter itself can be smaller.
