The Ultima II Filter is the best choice for home hobbyists and aqua professionals alike due to its impressive capacity and minimal, effortless maintenance. Independent laboratory testing confirms that the Ultima II filter is superior to three leading bead filter brands in setup, nitrification, back-washing and overall efficiency. It's perfectly designed for high flow rates, extreme fish loads and elevated feed rates.

Why Use a Biomechanical Filter?
To support aquatic life, it is essential to remove both ammonia and accumulated debris. The most efficient way to accomplish this is by installing an Ultima II biomechanical filter, which removes particles AND ammonia. Beneficial bacteria convert ammonia into harmless compounds.

How is the Ultima II Different from Bead Filters?
Other bead filters use a wax-based, plastic pellet that 
can take 6 weeks to begin eliminating ammonia. The smooth plastic encourages clumping, causing water and waste to pass around the large mass of beads and allowing untreated ammonia and solids to return to the pond. Breaking up those clumps of beads often means opening up the filter and poking at the clumps with a stick - inconvenient and messy.

The Ultima II uses a patented, non-wax-based plastic media that comes pre-seeded with natural bacteria so that it starts working within 2-4 weeks of installation! Its unique design prevents clumping and gives it the highest biofilm surface area of any product on the market, which allows the Ultima II to handle more load even though it is smaller than bead filters. When it comes to cleaning, the Ultima II patented cyclonic backwash separates the waste and flushes it out the waste line for easy cleaning. See it at work below!
