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
again!
• 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
Independent Laboratory Testing
Confirms Ultima Filters are the Best!
Gillespie Biomonitoring Labs, an independent, certified testing laboratory,
tested the Ultima II filter and the other three leading bead filters.
The Ultima II filter proved to be superior in all area’s
including setup, nitrification, back washing and overall efficiency.
These top-of-the-line filters are the best choice for fish
holding systems, aquaculture and koi ponds.

Patented Bio Tube Filter media has 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.
Maximum pond size is for water garden applications which typically have a light fish load. Use maximum pounds of fish column for aquaculture and fish holding systems where density of fish is much higher.
