AA200 Aqua Ultraviolet Ultima II Filter – 20,000 Gallon Pond Max

Ultima II Filters are superior to bead filters because of their patented bio-tube media which does not clump together like beads do. No need for a blower for back washing!

• Super easy to backwash – never get your hands wet!
• Unique filter media allows for high flow rates with minimal back pressure
• Compact filter can be buried in ground (up to control head) for easy hiding when used as a pond filter

Patented Bio-Tube Filter media has an extremely high surface area (one cubic foot of media has 750 square feet of surface area) for maximum filtration. This lightweight, non-clogging media is seeded with natural bacteria for quick filter start up after installation.
