*Extra shipping charges may apply*

The Aqua Ultima II Filter combines both biological and mechanical filtration in one compact body. Simply by rotating the valve the patented cyclonic backwash system does the dirty work for you. 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.

Patented Filter Media

Ultima filter media has the highest biofilm surface for bacterial growth, one square foot of media has 800 cubic feet of surface area. This unique media is also pre-seeded with beneficial bacteria to start colonization and quickly begin the conversion of 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 or channeling and won't stack or stick during backwashing. 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 multiport valve on top of the filter.
