AA40 Aqua Ultraviolet Ultima II Filter – 4000 Gallon Pond Max
Ultima 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.
