Experience superior filtration with the Aqua-UV Ultima II 4000 Bio-Media Bead Filter with 2" Valve

The Ultima II Bio-Media Filter is expertly engineered to meet the rigorous environmental demands of fish ponds. This advanced filtration system features lightweight media specifically designed for very high flow rates, ensuring optimal water quality. The tubular Bio-Media boasts low head loss and an exceptionally high biofilm surface area, promoting the growth of beneficial bacteria. Its unique "Y" shape interior and winged exterior protect the media during backwashing, while the patented backwash system prevents clogging, maintaining peak performance.

With three different sizes and random lengths and diameters, the Ultima II media avoids stacking, ensuring even distribution and maximum filtration efficiency. No other pressurized filter on the market can match the cleaning power of the Ultima II, which uses internal jets for easy maintenance. This makes it the ideal choice for both fish ponds and aquariums where high flow rates are desired. The patented Bio-Media offers unparalleled mechanical and biological filtration.

Patented Bio-Media

The Ultima II system's non-organic filter media is designed to foster bacteria growth without the drawbacks of conventional bead filters. Traditional filters often develop a second layer of bacteria, leading to anaerobic conditions that can harm your aquatic ecosystem. In contrast, the Ultima II's innovative media supports the growth of ammonia-oxidizing and heterotrophic bacteria, with over two million tiny shapes per cubic foot. This results in 750 square feet of surface area per cubic foot of media, providing exceptionally clear water. For maximum circulation, keep the hose short and minimize the pumping height on the discharge side of the filter.
