Description
Aqua Ultraviolet Ultima II 4000 Filter
The Aqua Ultraviolet Ultima II 4000 is a professional-grade biomechanical filter designed specifically for Koi ponds and water gardens up to 4,000 gallons. Renowned for its patented tubular media, the Ultima II provides the highest biofilm surface area for beneficial bacteria to thrive, effectively neutralizing ammonia and nitrite while simultaneously removing debris.
Unlike traditional bead filters that can clump or "channel" (where water finds a path around the media rather than through it), the Ultima II’s unique media design ensures even water distribution and consistent filtration. Whether you're managing a heavy fish load or a high-end aquaculture system, the Ultima II delivers the crystal-clear water and healthy ecosystem your aquatic life requires.
Key Features & Benefits

Superior Biomechanical Filtration: The patented media nitrifies fish waste faster and more efficiently than standard bead or foam filters.
-
No Channeling or Clumping: The ridged, tubular media is designed to trap solids without sticking together, ensuring the entire filter bed is utilized.
-
Minutes to Backwash: Maintenance is a breeze—simply rotate the multi-port valve to activate internal jets that separate waste from the media and flush it out.
-
Supports Heavy Fish Loads: Engineered to handle the high waste output of large Koi and intensive aquatic environments.
