Tetra Whisper Internal Aquarium Power Filter with BioScrubber

I initially ordered this filter in March 2021. I had it replaced after it broke during the summer, and the replacement just died as well. I'm not happy with this filter at all, it just stops working for seemingly no reason. The gaps on the intake are also large enough that it sucked up and killed two of my smaller fish. It's easy to put together and install, but I can't say anything positive beyond that. Going to toss it and try something else!

It’s a good filter for its price but disappointing in some areas. It may not be visually pleasing depending on your tank, it looks a bit too big for a 10gal. It is decently quiet and if you have a fan or something else, it’s drowned out. Kinda disappointed that the 5-10 gallon filter has a speed adjustment and this one doesn’t. If your on a budget it’s a pretty good filter.

I was really worried about the size of the whole thing but it cleaned up my foggy water and has kept it crystal clear since!

If you don't mind getting the original foam filters and not the updated BioScrubber filter, they work like normal. They self start back up if you have a power outtage, no need to prime back up. All ten are working perfectly as new and as long as the intake slots are submerged with water, they are strong enough to pull water the rest of the way up to keep water flowing if you want to do a partial water change and not have to turn them off. Great for fish with high oxygen requirements. I ordered ten of the Tetra Whisper Internal Aquarium Power Filter with BioScrubber, 20-40 gal. All ten of them had the original foam filters instead of the BioScrubber filters.

I had a large shipment of fish show up the same day my filters showed up, so I couldn't risk returning them and trying to find ten replacements locally on the same day. I contacted chewy customer service and they could not send me the missing BioScrubbers to complete my order, but wanted me to do a return and reorder. This was not feasible due to my fish needing them immediately. Just bad timing for getting not what I ordered. … more

I've had this filter for a few months now and I must say that it has done an AMAZING job at keeping the water in my turtle tank crystal clear. I was a little skeptical when I bought it but over time it has proven to be one of my best purchases ever for my little friends. Happy Turtles, Happy Life!

I think it's just a cheaper alternative for smaller tanks, it's definitely very quiet no problems there. But, it doesn't keep the water clean very long we also started noticing bubbles almost like soap but kinda like a foam as well not sure what that's about. Definitely will be looking into another one that will stay clean a bit longer and be a bit more effective. I've seen other say it keeps it clean for quite a while but I've changed the filer and had to clean the whole tank more than three times in one month and, it's only a GALLON fish tank. You'd think a 5 to ten filter would keep always a gallon cleaner than it does.

I’m on my 4th one of these. They’re quality, fairy eat to clean, and reasonably priced. They don’t last forever, but you can get the filter refills pretty much anywhere and they are worth it for the length of time they do last which for me has been generally about 6months.

Chewy offers great prices and fast shipping. The closest pet store to where I live is about 25 minutes away and it's very small so the prices are very steep and she's prices are almost half of what I would pay after driving all that way. They have a bigger selection and very fast shipping it's definitely worth it and I would definitely recommend this site for anything that's shippable!!

This filter is the best we have found by far. It keeps the water clean and is actually quiet! We ended up replacing all three filters in our 3 aquariums with this filter because it is so quiet.

It does filter but I have found trouble with the way is hangs on the tank and tends to fall off the side of the tank frequently.I have also found it it causes a lot of micro bubbles in the tank if not hanged on at a specific angle but when hanged at said angle and when stays on side of tank it does filter the water well and does it’s job.
