## Description

The Tetra® Whisper® Internal Power Filter for 5- to 10-gallon aquariums uses medium Tetra® Whisper® Bio-Bag® Filter Cartridges with Stay Clean™ technology. Tetra® filters feature quiet operation and effective three-stage filtration: mechanical, chemical and biological. The filter cartridge floss screens out dirt and debris. Ultra-Activated® carbon inside the filter cartridge removes odors and discoloration. Our premium wood-based carbon offers superior filtration power, clearing odors, tannins and dye more effectively than coconut shell-based filters. Finally, biological filtration works to eliminate toxic ammonia and nitrate. The powerful Tetra® Whisper® Internal Power Filter motor filters up to 85 gallons per hour. Stay Clean™ technology helps reduce buildup on aquarium glass, binds small particles to make them easier to filter, and helps stabilize pH to promote a clean, healthy environment for your fish. The Tetra® Whisper® Internal Power Filter’s space-saving design is easily hidden by aquarium decor and allows your aquarium to be positioned as close as one inch from the wall. The adjustable, universal clip allows for a variety of setups to easily adjust to high or low water levels. With quiet, convenient filtration hidden inside the aquarium, caring for your fish is easy and efficient.

Review: Love, Love This Filter! - Okay so... I have a 20 gallon temporarily for my 4 inch turtle. I accidentally bought the smallest of this tetra filter, so I bought the medium sized one in it's place. I had only had the tank filled halfway anyway since my turtle was only 1.5 inches at this point. Mind you I didn't realize how fast they grow, and had no idea that Its recommended to have a filter that can filter 2 to 3x the tank size. So I decided to keep both filters in my tank. One on each side. Even though I still don't reach the recommended filter size, my water now almost filled to the top, stays absolutely clean. Turtles are pretty messy so I still have to do the weekly cleanings and all that extra stuff that apparently those who spend hundreds of dollars on filters still have to do as well. I don't know if this is some kind of luck thing, I don't know if maybe my turtle just isn't that dirty (yea right, I see him)... but I'm actually not looking forward to switching out my filter for the 'recommended' filter size, as these filters work so good. I love them. They are both very quiet. Aside from the sound of the water falling back in.. I mean it sounds like a waterfall. Who doesn't want to hear a waterfall? I love it. This can also be prevented by raising the water level or lowering the filter itself. Basically the closer it is to the water, the quieter it is. Such a simple device, yet so beautifully sufficient. The little one stopped working at one point and I thought... welp there you go! Get what you pay for. But nope! Removed the base, pulled out the magnetic spring propeller and tube, cleaned it out and like magic it started right up as soon as I plugged it back in. Love how easy it is to replace the filters. The filters themselves are great and definitely hold on to some dirtiness. One thing I'll say is there is quite a bit of unused empty space. I now take advantage by adding some extra media, but I must say that these filters work great even without the extra. Love this filter and would recommend above any other filter.
Review: Great Budget Filter—Super Easy to Use - I love this filter! It is super easy to set up and works great. I literally just clipped it inside my tank, plugged it in, and it was good to go. It keeps the water crystal clear and is surprisingly quiet as long as you keep your water level up. Perfect for small tanks and anyone who wants a no-fuss setup. Definitely recommend!

## Questions & Answers

**Q: What size replacement filter cartridge for this unit...small, med?**
A: The Tetra Bio-Bag Large (formerly known as Regular) are the exact same as the filter bag supplied with the Tetra Whisper In-Tank filter 20i. I got both from Amazon: filter $11.89; 12 cartridges $12.28. These filters last a long time, can be cleaned and reused. For my purpose, this filter has been great.

**Q: Where can I just get the Bioscrubber?**
A: Hello. You can get it at a pet store, amazon has some, grocery stores with a pet section...they are pretty easy to find.

**Q: Would a small fish get sucked up in this filter? I have a 2 month old beta who is just recently getting color fins but still very small**
A: Yes. I had 4 neon tetras and all 4 ended up getting sucked into the filter and the spinning fan mechanism blended them into multiple pieces. It happened the first night, I woke up and 4 fish were missing. I found them in the filter :(

**Q: Would this filter be too strong for a Betta in a 10 gallon tank?**
A: Yes, it would be fine.  It is rated at 90 GPH which is the appropriate flow rate for a 10 gallon tank.  Bettas are not the strongest swimmers, it is true, but typically handle filtration fine, as long as it is placed at one end of the tank so they have room to move away if necessary. They eventually adapt and will often play in the flowing water.  Initially, you might want to place tall plants or tall décor in front of it to break up the flow until the betta becomes accustomed to it.

### ⭐⭐⭐⭐⭐ Easy Replacement Filter That Got My Fish Tank Back on Track
*by C***I on July 23, 2026*

The pump on my old filter died, and I could immediately tell my fish were not as happy. My 5-gallon tank was also starting to look dirty, so I knew I needed a replacement quickly. I ordered this Tetra water filter and was able to get it overnight. Installation was very easy—the instructions were clear, and I had it up and running without any trouble. I especially love that the replacement cartridge is a simple, single item. My previous filter had three separate replacement pieces that were difficult to keep track of, hard to find, and easy to forget to reorder. I haven’t had this filter for a long time yet, but so far I’m very happy with how easy it was to set up and how well it keeps the tank looking clean and fresh. It’s a straightforward, convenient solution that makes maintaining a fish tank much easier. I would definitely recommend it to anyone needing a reliable replacement filter.
