Review: Love, Love This Filter! - Okay so... I have a 20 gallon temporarily for my 4 inch turtle. I accidentally bought the smallest of this tetra filter, so I bought the medium sized one in it's place. I had only had the tank filled halfway anyway since my turtle was only 1.5 inches at this point. Mind you I didn't realize how fast they grow, and had no idea that Its recommended to have a filter that can filter 2 to 3x the tank size. So I decided to keep both filters in my tank. One on each side. Even though I still don't reach the recommended filter size, my water now almost filled to the top, stays absolutely clean. Turtles are pretty messy so I still have to do the weekly cleanings and all that extra stuff that apparently those who spend hundreds of dollars on filters still have to do as well. I don't know if this is some kind of luck thing, I don't know if maybe my turtle just isn't that dirty (yea right, I see him)... but I'm actually not looking forward to switching out my filter for the 'recommended' filter size, as these filters work so good. I love them. They are both very quiet. Aside from the sound of the water falling back in.. I mean it sounds like a waterfall. Who doesn't want to hear a waterfall? I love it. This can also be prevented by raising the water level or lowering the filter itself. Basically the closer it is to the water, the quieter it is. Such a simple device, yet so beautifully sufficient. The little one stopped working at one point and I thought... welp there you go! Get what you pay for. But nope! Removed the base, pulled out the magnetic spring propeller and tube, cleaned it out and like magic it started right up as soon as I plugged it back in. Love how easy it is to replace the filters. The filters themselves are great and definitely hold on to some dirtiness. One thing I'll say is there is quite a bit of unused empty space. I now take advantage by adding some extra media, but I must say that these filters work great even without the extra. Love this filter and would recommend above any other filter. Review: I love these. Still going strong after 5 years. Bigger one and smaller one - I have used these for so many years for little tank setups and my turtle and snails etc. Always work super great and super quiet! Plus they are cheap. No brainer imo. I'm sure theres a faulty one here n there as with anything but keep the propeller clean like any other pump and dont let the filters get too overflowing clogged and you'll be happy I promise. Also with filters of any kind try to get one rated for more than you actually have so the filter doesn't get overwhelmed. Even the filters are cheap for a box of 12 for like $13. Cant go wrong!! 10/10 ## Features - UNIVERSAL DESIGN Tetra Whisper 10i Internal Filter is an all-in-one water pump and water filter system - INTERNAL FILTER Mounts on the inside of your aquarium with clip (included) - CATCHES DEBRIS Dense dual-sided mesh filters debris and fish waste - AERATES WATER filters up to 80 GPH while oxygenating water - CONVENIENT DESIGN Uses medium easy to change Bio-Bag cartridges filter mounts inside aquarium making it possible to place tank flush against the wall ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0002DHYF4 | | ASIN | B0002DHYF4 | | Best Sellers Rank | #1,452 in Pet Supplies ( See Top 100 in Pet Supplies ) #2 in Aquarium Filters | | Brand Name | Tetra | | Color | Black | | Customer Reviews | 4.3 4.3 out of 5 stars (22,217) | | Date First Available | June 9, 2004 | | Department | Unisex-Adult | | Global Trade Identification Number | 00046798258162 | | Included Components | Tetra Whisper Internal Power Filter 5 To 10 Gallons, For aquariums, In-Tank Filtration With water pump , Black | | Is Discontinued By Manufacturer | No | | Item Type Name | Tetra Whisper Internal Filter | | Item Weight | 1.1 Pounds | | Item model number | AQ-65816 | | Manufacturer | Tetra | | Manufacturer | Tetra | | Material Type | Acrylonitrile Butadiene Styrene (ABS), Polypropylene (PP) | | Model Number | AQ-65816 | | Product Dimensions | 4.25 x 4 x 8 inches; 1.05 Pounds | | Product Style | Submersible | | UPC | 046798258162 | | Unit Count | 1 Count | ## Product Details - **Brand:** Tetra - **Color:** Black - **Global Trade Identification Number:** 00046798258162 - **Item Weight:** 1.1 Pounds - **Manufacturer:** Tetra - **Material:** Acrylonitrile Butadiene Styrene (ABS), Polypropylene (PP) - **Specific Uses For Product:** Active - **Style:** Submersible - **UPC:** 046798258162 ## Images ![Whisper Internal Power Filter 5 To 10 Gallons, For aquariums, In-Tank Filtration, Black - Image 1](https://m.media-amazon.com/images/I/710OiJv94DL.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 décor in front of it to break up the flow until the betta becomes accustomed to it.
