Aqua Ultraviolet Ultima II 2,000 Pond Filter

To maintain a healthy pond ecosystem, it is important to remove both ammonia and accumulated debris.  The Ultima II filter series combines both biological and mechanical filtration in one compact body.  The patented media has the highest biofilm surface for bacterial growth.  This beneficial bacteria converts ammonia into harmless compounds which are returned to your pond water. As a mechanical filter, the dense bed of ridged media traps solids efficiently without clumping.  Cleaning is a simple process with the integrated backwash cycle.  By simply rotating a valve, internal jets in the filter are activated, which separate out the waste from the media, sending it out the waste line.
