Tetra Pond BP-1500 Small Bi0Active Pressure Filter

For maximum flow use with 1-1/2" ID tubing. 

New from Tetra, the Bio-Active pressure filter has been re-engineered for maximum bio filtration resulting in a clear and healthy pond. New vortex internal pumping jets ensure maximum water-to-media contact to support bacterial growth and provide for superior bio-activity. The rugged construction of this filter is built to last. The unique open profile bio-activators will not clog and give you the most surface area possible. With no foam to clog, the simple back flush feature keeps your filter performing in peak condition with no need to open the filter for cleaning.

Each pressure filter is sold as either a stand-alone unit or with an integrated UV clarifier to provide permanent control of suspended algae and reduce green water.
