Designed for quiet operation and space efficiency, it mounts inside the aquarium with included clips, allowing tanks to sit flush against walls. Featuring dual-sided mesh filters and easy-to-change Bio-Bag cartridges, it ensures clean, oxygen-rich water for healthier aquatic environments. ## 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.

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.
