Featuring open-profile bio-activators for maximum beneficial bacteria growth and an easy backflush valve for quick, mess-free cleaning, this filter ensures a healthy aquatic environment with minimal effort. Trusted since 1951, Tetra delivers reliable pond care with proven performance. ## 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. Review: Great filter easy to maintain and has a long life - I have had one of these filters for around 8 years so I just purchased another one because I feel it could be at the end of its life. It is super easy to maintain and keep the pond clean. I love the backwash feature, but after turning off the pump, we take the hose out of the water else the backwash (as you turn it on and off) will dump tons of dirt into the pond. So just take the hose out and do the backwash on and off a few times until you see is coming clean at both ends. Also, we normally wash the whole filter probably every 8 weeks. We made a gigant container (a square with 4x2s) with hardware wire as the floor of that container. We dump the little white piece onto this made up strainer and hose them really well. Makes the job super easy... but you lose the good bacteria every time you do a full filter clean. We fill the filter with the pond water and works fine. My only concern eith this filter is the hoses could become lose even with clamps and i am terrified of obe day finding the pond with no water. I am trying to find better connectors that mire securely attach the hoses to the in and outlets. The filter last longer if it is covered from direct sun too. I have the pump also from Tetra and both of them work great together. Very pleased. My 7 koi fish are all happy and healthy. Review: Took a little while to clear the pond but it looks better than ever! - We have a 1500 gallon pond that we've been just sort of winging it since we bought the house 4 years ago. The summers are hot in NC and the algea gets out of control. We also have a lot of trees dropping debri in the pond. We finally got in there and scooped a lot of the crap out which made the water very murky. We had a pump and filter combo from AquaSource that was so nasty to clean out. In the summertime we would have to clean it two or three times a week just to get the water to circulate through the pump. On a local Facebook group I asked what kind of pump I could use that would not get clogged up and everyone suggested the Tetra large debris pump with this filter hooked up to it. The first couple days we were pretty disappointed that we didn't see much clarity. However, after 3 weeks the pawn looks better than it's ever looked. Because the pond was so scummy and murky to begin with, I did the back flush every other day to clean out the filter and added fresh water to the pond since the backflush causes a lot of water loss into the yard. So we've had it for about a month now and the back flush option is really awesome. One thing to be mindful of is the attachment sizes of this unit are rather large (1 1/4 and 1 1/2). It's hard to find pond tubing that size locally And we also ended up having to buy a new waterfall box because our old waterfall box only had a 3/4 in max inlet. So if you end up going with this filter, I would definitely recommend buying your hosing in any other accessories you need online. We used the Tetra large debris handling 3000 gallon pump with this and it's working great. ## 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 350 Reviews | ## Images ![Tetra Pond Bio-Active Pressure Filter, for Ponds Up to 1500 Gallons - Image 1](https://m.media-amazon.com/images/I/7131YrfTobL.jpg) ![Tetra Pond Bio-Active Pressure Filter, for Ponds Up to 1500 Gallons - Image 2](https://m.media-amazon.com/images/I/815KYhcBO2L.jpg) ![Tetra Pond Bio-Active Pressure Filter, for Ponds Up to 1500 Gallons - Image 3](https://m.media-amazon.com/images/I/91ggAbCs4qL.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. Where do you order the KIT? ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great filter easy to maintain and has a long life *by L***A on March 16, 2021* I have had one of these filters for around 8 years so I just purchased another one because I feel it could be at the end of its life.

After doing some research I decided to try this filter along with a Tetrapond pump. Wow! What a difference it made in about 10 days. No more clogs in the fountain and the water clarity settled down and is easy to maintain. Very easy to clean as well. Note that this filter is MUCH bigger than it appears. I was able to hide it under an upside down half oak barrel, that now has a potted plant on it. For reference, my pond is 12 x 12 and 3 feet deep. Holds an estimated 2,200 gallons. ## Frequently Bought Together - TetraPond Bio-Active Pressure Filter, For Ponds Up to 1500 Gallons - Sealproof Kinkproof 1-1/2" Dia Waterfall, Pond Tubing, 1-1/2-Inch ID, 20 FT, Black Corrugated PVC Strong Flexible Tubing, Made in USA --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ro/products/8016537-tetra-pond-bio-active-pressure-filter-for-ponds-up-to](https://www.desertcart.ro/products/8016537-tetra-pond-bio-active-pressure-filter-for-ponds-up-to) --- *Product available on Desertcart Romania* *Store origin: RO* *Last updated: 2026-10-19*
