Ratings & Reviews
Excellent flow and quiet too.
I already own a junior one for my 5-1/2 gallon quarantine tank and have no issues. I bought this one for my newly set up 10 gallon tank and have no issues with it. It is very quiet in operation.
Best filter on the market
I have 5 aquariums of varying sizes, and have kept fish for a very long time. Over the years I have tried a variety of different filters, and this is the best, by far. I use this size in a 10 gallon tank, and it keeps the water crystal-clear, and is quiet, efficient, and durable. I will never try another brand - this is the best!
Got this for my 20gal tank and it works great water is clear , It's super quiet and you can choose the flow...great filter
I needed to step up my current Tetra filter and am using this one for my 10 gallon tank. I've always used Tetra filters and this one is good for the cost.

While you may believe this is a great filter, it is not packaged with the correct impeller with intake tube. I needed two deliveries from Tetra to make it right. I will not buy another Tetra product.
Whisper does not work
Something is wrong with the tube as it does not seem to fit properly. As a result, it does not function and is extremely noisy. I have spent more of my time with this than it is worth, and now I have to spend more to return it.
Whisper now works
At first I was very upset because the tube didn't seem to fit properly and it was extremely loud. But after I pushed the tube all the way down, it now works and is whisper quite.
