## 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.

## 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.
