The Ultima ll Difference:

Unique tubular  design protects beneficial
bacteria while dislodging unwanted debris.
Media never needs to be replaced. Units can be
buried in earth up to the valve. No channeling,
and minutes to backwash. Pre-sealed with bacteria
to quickly start colonization, and combines
both biological, and mechanical filtration.
Ultima ll Filters are designed for, high flow rates,
extreme fish loads, and elevated feed rates.
Blower not needed, because internal jets allow for
efficient cleaning of the filter media.
