## Overview

The Whisper Internal Power Filter is a compact, in-tank filtration system designed for aquariums up to 10 gallons. Featuring an air-driven motor that filters up to 80 gallons per hour while oxygenating water, it mounts inside the tank for a flush, space-saving profile. Equipped with dual-sided Bio-Bag cartridges, it efficiently traps debris and fish waste, ensuring a clean and healthy aquatic environment with minimal noise.

## Description

For the ultimate in convenience and quiet, choose a Whisper In-Tank Filter. These filters mount on the inside of the aquarium, rather than hanging from the outside -- making it possible to place the tank flush against a wall. In-Tank Filters are unusually quiet, since the motor is under the water. Offering the same quality and performance as an external filter, the Whisper In-Tank Filter will function in as little as 2 inches of water -- making it ideal for turtle tanks, or for creating a waterfall inside the tank.The Whisper In-Tank filter features adjusts easily to high or low water levels with mounting suction cups and/or bracket. Each filter comes with one pre-assembled Whisper Bio-Bag filter cartridge.

Review: Disappointed !!! - Worst filter, don’t buy this…the motor dies in few hours and doesn’t work anymore.
Review: Very bad experience - Motor is not woking properly, very big broken sounds is coming out from the motor, request desertcart to refund, very sad.

## 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.
