Aqua Ultraviolet AAV50003 Ultima II 4000 Filter

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.

• This action blasts the media apart, then lifts and spins it, separating the waste and flushing it away
• The Ultima II patented tubular media design has the highest surface area on the market to grow beneficial bacteria
• These bacteria break down fish waste, creating a safe healthy environment. Min Flow Rate-2,000 GPH. Max Flow Rate-4,500 GPH
• Note: The filter media is not supposed to be included with this item. It is sold separately.
