Tetra Bio-Active BP2500 Filter & DHP4200 Debris Handling Pump Kit

The Bio-Active Pressure Filter works to keep your pond clean and healthy with both mechanical and biological filtration. This easy-to-use filter features a unique open profile bio-activator that provides a large surface area and unrestricted water flow to all surfaces for improved filtering. A simple back flush valve allows for fast cleaning. 

• Open-profile Bio-Activators offer superior filtration and back flush performance
• A layer of bio-film containing beneficial bacteria will remain on the bio-reactors
• Use with pumps between 2,500 - 4,500 GPH
• Accepts 1-1/4" and 1-1/2" tubing

We only recommend using magnetically driven (mag-drive) or asynchronous drive pumps for this filter.
