To support aquatic life whether at an aquaculture facility, backyard pond or large aquarium system it is essential to remove both ammonia and accumulated debris. The most efficient way to accomplish this is by installing an ultraviolet pond filter like the Ultima II Biological Aqua Filter. The patented UV bio filter media has the highest biofilm surface for bacterial growth; these beneficial bacteria convert ammonia into harmless compounds. The dense bed of ridged media in the UV bio filter traps solids without clumping. Internal jets in the ultraviolet pond filter are activated during the backwash separating the waste from the media and sending it out the waste line.

The Ultima II 30,000 Bio-Mechanical Filter, an Aqua Ultraviolet pond filter, takes only minutes to backwash, and can handle heavy fish and feed loads. Equipped with ‘cyclonic’ backwashing, Ultima II features Bio-Tube Aqua Media. These media are of tubular design, which aims to protect bacteria while dislodging unwanted debris. Also, lightweight in design for very high flow rates.

The ‘Y’ shape and the wings on the outside affords a protective surface under the backwashing and the easy to use backwash system will keep the UV bio filter media from clogging. One cubic foot of Ultima II media is equal to 750 sq ft of surface area.

Cleaning the filter of the ultraviolet pond filter is done by internal jets. The Ultima II Aqua Filter tested and used by MIT (Massachusetts Institute of Technology) has outperformed the competition. Tested side-by-side against all bead filters on the market, the Ultima II filters have been found to be superior.

The Ultima II Aqua Filter, which is seeded with bacteria, works like a centrifuge. The valve is rotated so the backwash will set the filter into cyclonic motion. A valve located inside the ultraviolet pond filter closes, which then diverts the water through the jets, sending the media spinning out to the walls of the filter, while dislodging the waste, causing it to separate and be sent out through the waste outlet.

The Ultima II Aqua Filter will work with any pump appropriate for the pond in question. The Ultima II’s Bio-Media design is light enough so that the water from the pond will completely and quickly backwash the UV bio filter.

Note: Use Appropriate Pump for Filter Size (E.G. If you purchase a 4000 Gallon Ultraviolet Pond Filter, use a pump that will give you 4000 GPH at your Total Dynamic Head (10’ of pressure head plus vertical head height plus friction head (length and inside diameter size of hose with fittings such as elbows) for the best backwash. In addition, the Ultima II Filters should not be used with pipe dope inline as it will break down the valve of the Ultima Filter. Teflon tape is recommended.
