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. 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.
