Featuring a 3-stage filtration system including cartridge floss and ultra-activated carbon, it effectively removes debris, odors, and discoloration. Its space-saving internal clip design allows tanks to be placed just 1 inch from walls, while adjustable mounting ensures optimal performance at various water levels. Ideal for professionals seeking a sleek, efficient, and low-maintenance filtration solution. ## 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. ## Features - INTERNAL POWER FILTER: Tetra Whisper Internal Power Filter for 10- to 30-gallon aquariums uses large Whisper BioBag filter cartridges that are easy to change. - QUIET 135 GPH MOTOR: The internal pump efficiently filters up to 135 gallons per hour. - POWERFUL FILTRATION: Water flows through the cartridge floss, trapping debris and fish waste, while Ultra-activated carbon helps remove odor and discoloration. - SPACE-SAVING DESIGN: Your aquarium can be 1” from the wall with the internal filter designed to clip directly on your aquarium wall and be hidden by dΓ©cor. - EASILY ADJUSTABLE: Adjustable clip allows for a variety of setups to easily adjust to high or low water levels. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0002DHYG8 | | Best Sellers Rank | #1,411 in Pet Supplies ( See Top 100 in Pet Supplies ) #2 in Aquarium Filters | | Brand Name | Tetra | | Color | Black | | Customer Reviews | 4.2 4.2 out of 5 stars (22,526) | | EU Spare Part Availability Duration | 1 years | | Global Trade Identification Number | 00046798258179 | | Included Components | Aquaria 75025817: Tetra Whisper 20I Internal Filter | | Item Dimensions L x W x H | 10.2"L x 4.9"W x 10.2"H | | Item Type Name | Aquarium Filter | | Item Weight | 1.5 pounds | | Manufacturer | Tetra | | Manufacturer Part Number | AQ-65817 | | Manufacturer Warranty Description | See label | | Material Type | 100% Polyester | | Model Number | 25817 | | Number of Items | 1 | | Number of Packs | 1 | | Product Style | Submersible | | Specific Uses For Product | Indoor | | UPC | 046798258179 | | Unit Count | 1 Count | ## Product Details - **Brand:** Tetra - **Color:** Black - **EU Spare Part Availability Duration:** 1 years - **Global Trade Identification Number:** 00046798258179 - **Item Weight:** 1.5 pounds - **Manufacturer:** Tetra - **Material:** 100% Polyester - **Number of Packs:** 1 - **Product Dimensions:** 10.2"L x 4.9"W x 10.2"H - **Style:** Submersible ## Images ![Tetra Whisper 135 GPH Internal Power Filter For Aquariums | For Fish Tanks Up To 30 Gallons, Whisper Quiet, 3-Stage Filtration, Space-Saving Internal Filter Clips on Tank - Image 1](https://m.media-amazon.com/images/I/81g1VKwt4dL.jpg) ## Available Options This product comes in different **Size** options. ## 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 dΓ©cor in front of it to break up the flow until the betta becomes accustomed to it.
