Ultima II Filter, 4,000, with 1-1/2″ Valve

The Ultima II is specifically engineered to meet the environmental demands of aquatic life. Our patented Ultima filter does the work of two, combining biological and mechanical filtration into one compact package. The internal components are designed to accommodate high flow and heavy solids that occur naturally when aquatic life is present. The patented cyclonic action is generated by jets activated during the backwash cycle. Note: The filter media is not supposed to be included with this item. It is sold separately.
