Its easy backflush valve streamlines maintenance, ensuring continuous optimal water quality without hassle. Trusted since 1951, Tetra delivers reliable, efficient pond filtration that keeps your aquatic environment clear and healthy. ## Description Since 1951, Tetra has developed the world’s most comprehensive body of fish food knowledge, and fishkeeping enthusiasts have looked to the brand for products and solutions that add ease and beauty to their home. Whether you're an experienced hobbyist or just starting out, Tetra has everything you need – from a large variety of quality fish food and innovative equipment to test kits and decor. The Tetra® Pond Bio-Active Pressure Filter helps keep pond water clear and healthy. Using both mechanical and biological filtration to help maintain clear and healthy pond water, this easy-to-use filter features unique, open-profile bio-activators to provide a large surface area to clean with maximum efficiency as pond water is forced through. After running through the cycle, the filtered water is returned to the pond by waterfall or stream. Once your pond is clean, the last thing on your mind is getting your hands dirty cleaning out the filter. That’s why we designed an easy backflush valve that can help you complete the cleaning process efficiently. You won’t even need to open up the filter; just remove the backflush cap and you’re good to go. Backflushing prevents dirt buildup so that all surface areas of the bio-activator media can remain active for biological activity. With its robust functionality, this filter works for ponds up to 1,500 gallons. ## Features - MECHANICAL FILTRATION: Pond water flows down through the bio-activators, which remove suspended debris and dirt from the water - BIOLOGICAL FILTRATION: Maximized surface area on the bio-activators allow beneficial bacteria to colonize and attack harmful pollutants in the water - EASY TO CLEAN: The easy backflush valve makes the cleaning process highly efficient - CAPACITY: This filter works for ponds up to 1,500 gallons - TETRA PRODUCT: You can trust your pond to Tetra products - Ships in Certified Frustration-Free Packaging ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.0 out of 5 stars 349 Reviews | ## Images ![Tetra Pond Bio-Active Pressure Filter, for Ponds Up to 1500 Gallons | 2-Step Mechanical & Biological Filtration, For Clean & Healthy Ponds, Easy To Clean With Backflush Valve - Image 1](https://m.media-amazon.com/images/I/7131YrfTobL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: How do you winterize this in an area that gets below freezing?** A: I live in NJ and every fall I shut the flow valve to the filter - I have a waterfall that I let run for a few more weeks until we start getting ice - disconnect the filter from the water line. I then clean it out - in particular the material inside that the good bacteria grows on - and place it in the garage to dry out for a few weeks. I then take it down into the cellar for the winter. I know of no way of winterizing it in place and leaving it ourside for the winter. The water will freeze and I wouldn't want to add even "non-toxic" anti-freeze to any pond equipment. Hope that helps. **Q: I still need a pump for this right?** A: Yes you do. I use a Tetrapond DHP4200 Debris Handling Pump. Don't use a pump stronger then that. **Q: am going to buy the BP2500. Want to know what inlet and outlet pipes diameter are?** A: Inlet/Outlet 1.25 in., 1.5 in./1.25 in., 1.5 in. **Q: Does anyone know the size of the large oring included in the filter? I need to replace the original one I have and the kit is $34 for a lot of extra parts I don't need.** A: I believe I have the same filter problem and the O ring measures 12 inches across. does this sound like it is the right one? I need to replace it also.
