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 Ultima II biomechanical filter. The patented media has the highest biofilm surface for bacterial growth. The beneficial bacteria convert ammonia into harmless compounds. In field and independent laboratory testing the Ultima II filter with its patented media is the first to nitrify fish waste.

The dense bed of ridged media traps solids without clumping. Internal jets in the filter are activated during the backwash separating the waste from the media and sending it out the waste line. Backwash is performed simply by rotating the valve.
