Aqua Ultraviolet Ultima II 20,000 Pond Filter, 2" Ports (MPN A50119)

The Ultima II Filters are specifically created to handle high flow rates, extreme loads, and elevated rates. These filters are essential for maintaining the well-being of aquatic life in various settings, including aquaculture facilities, backyard ponds, and large aquarium systems. They effectively remove both ammonia and accumulated debris in applications ranging from 500 to 60,000 gallons. One of the standout features of the Ultima II Filters is the "cyclonic" backwashing system. This system utilizes Bio-Tube Aqua Media, which is designed in a tubular shape to protect bacteria while dislodging unwanted debris. By simply rotating the valve handle, the patented cyclonic backwash system automatically cleans the filter within minutes using internal jets. This combination of biological and mechanical filtration is packed into one compact body. The Ultima II Filters offer several advantages, such as their ability to handle high flow rates, withstand extreme fish loads, and accommodate elevated feed rates. Additionally, they are equipped with a unique patented tubular bio-media that prevents clumping. Another benefit is the compact design of the filter body, which allows it to be buried if desired. These features make the Ultima II Filters highly efficient and reliable tools for maintaining water quality in a variety of aquatic environments.
