Combining mechanical and biological filtration, it uses open-profile bio-activators to maximize surface area and water flow for superior cleaning. Its easy-to-use backflush valve simplifies maintenance by flushing out debris without disassembly. Packaged in eco-friendly, frustration-free materials, this filter ensures your pond stays crystal clear with minimal effort. ## 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 2,500 gallons. Review: Fantastic fix for pond! - I was struggling to keep my new pond clean and free from algae and my previous pump clogged literally after 1 week. 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. 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 and biological filtration to help maintain clean and healthy pond water - Backflush valve for fast cleaning - Bio-activators provide large surface area and unrestricted water flow for improved cleaning - For ponds up to 2500 gallons - 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 2500 Gallons - Image 1](https://m.media-amazon.com/images/I/71LN1MncpaL.jpg) ![Tetra Pond Bio-Active Pressure Filter, for Ponds Up to 2500 Gallons - Image 2](https://m.media-amazon.com/images/I/91ggAbCs4qL.jpg) ![Tetra Pond Bio-Active Pressure Filter, for Ponds Up to 2500 Gallons - Image 3](https://m.media-amazon.com/images/I/91fzpjB6yDL.jpg) ![Tetra Pond Bio-Active Pressure Filter, for Ponds Up to 2500 Gallons - Image 4](https://m.media-amazon.com/images/I/815KYhcBO2L.jpg) ![Tetra Pond Bio-Active Pressure Filter, for Ponds Up to 2500 Gallons - Image 5](https://m.media-amazon.com/images/I/91+LAaduriL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Fantastic fix for pond! *by R***0 on September 7, 2024* I was struggling to keep my new pond clean and free from algae and my previous pump clogged literally after 1 week.

I have a 1500 gph pump and the filter works fine. Even when I flush it, I get lots of debris flushed out. Not sure how the 3500 gph pump would make it better. I think the sellers could put this information on their sites so others could see it at a glance. I love the filter and it helps keep my pond clean! It was easy to install. I dug a hole, placed a LARGE flower pot in the hole, placed 2 bricks in the bottom and set the filter on top of the bricks. This will make taking it out for the winter much easier. This filter is easier to clean than the one I had IN the pond. I use that filter to keep large leaves out of the pump. ## Frequently Bought Together - TetraPond Bio-Active Pressure Filter, For Ponds Up to 2500 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.kr/products/4606203-tetra-pond-bio-active-pressure-filter-for-ponds-up-to](https://www.desertcart.kr/products/4606203-tetra-pond-bio-active-pressure-filter-for-ponds-up-to) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-08-18*
