Combines both biological and mechanical filtration in one compact body. Simply by rotating the valve the patented cyclonic backwash system does the dirty work. In just minutes the internal jets clean the filter for you. Ultima II Filters are designed for high flow rates, extreme fish loads, and elevated feed rates.
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.

I use this filter for my 6000 gallon Koi pond and it's great. It's been working for just 1 week and my water is now crystal clear and clean. The backwash is very easy. Backwash, drain water, fill back water only take me 5 min to do instead of what it was before which took me an hour at least.
They honestly know the industry of all their products they sell. Ben answered all my questions for my pond. I look forward to working with them in the future.
