Its internal clip mount allows tanks to sit flush against walls, blending seamlessly into your space while simplifying maintenance with easy-to-change cartridges.

## Description

Product Description               The Tetra® Whisper® 10i Internal Filter for aquariums is the ultimate in quiet, convenient 3-stage filtration. This submersible filter mounts on the inside of the aquarium, rather than hanging from the outside, making it possible to place the tank flush against a wall and easily hide with tank décor. The air pump (included) provides bubbles that move water through the filter, efficiently filtering and oxygenating your aquarium. The water flows through Ultra-Activated® carbon, absorbing odors and discoloration, as well as through the dual-sided mesh of the Bio-Bag® Filter, trapping debris and fish waste. Filters up to 80 GPH while oxygenating water. The Tetra Whisper 10i Internal Filter adjusts easily to high or low water levels with a mounting clip. Each unit includes the filter, air pump, 2 feet of airline tubing and one medium Tetra Whisper Bio-Bag Filter cartridge (change monthly – replacement filter cartridges available). For 3-10 gallon tanks. 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.

## 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.

### ⭐ not suitable for uk 240v
*by D***R on 24 February 2025*

this as an americanfilter with a 110 v pump. uk is 240v. pump breaks fast when plugged in to uk mains. why is this advertised in uk

### ⭐ Broke down within hours of plugging in
*by C***A on 9 June 2024*

The pump stopped working after 6 hours of being plugged in, came with a European plug on it. Brought a new adapter plug thinking it maybe my old one was the problem and still didn't work. £30 wasted, thank goodness my fish survived.

### ⭐ Broken the next day
*by S***R on 6 July 2023*
