Known in the industry as the easiest filter to maintain, the Aqua Ultima II Series takes just 5 minutes a week to backwash. Gone are the days of dismantling your filter and scrubbing pads. The Ultima II Bio-mechanical filter, traps and converts fish waste, ammonia, into a substance that is harmless to fish called nitrates. Nitrates can then be used by the plants in the pond.

To provide a healthy ecosystem for koi in a pond, quarantine tank or large aquarium, it is essential to remove both ammonia and accumulated debris. The most efficient way to accomplish this is by installing an Aqua 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 Aqua Ultima II 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.
