The Tetra Whisper internal aquarium filter is the ultimate in quiet, convenient 3-stage filtration. The dual-sided mesh of the Bio-Bag® catches debris and fish waste while the activated carbon absorbs odors and discoloration. Biological filtration is provided by the Bio-Scrubber. Bio-Scrubber's anti-clog design provides complete biological filtration with the convenience of less maintenance. Because the Bio-Scrubber has a solid back, water is forced to flow evenly over the bacteria-rich bristles. The filter is submersible. 

NOTE: The filter now comes with a clip to hold the filter. If suction cups are needed please contact Consumer Services at 1-800-322-1266.


This product comes in the following sizes:
Whisper 3i - 20 GPH
Whisper 10i - 80 GPH
Whisper 20i - 125 GPH
Whisper 40i - 170 GPH
Rated 1 out of 5 by from Terrible filter The suction on this filter is by far the worst i have ever seen. Even after two week of having it I have lost two whole tanks of fish thanks to this product. The water is constantly cloudy and/or slightly brown. That is even after a partial water changes or even total tank cleaning and filter cartage change. I even changed fish food brands to see if that would help, but sadly no. I Will not be buying this product again.

Rated 1 out of 5 by from Very noisy I bought this a few days ago and already don’t like it. The air pump isn’t very nosy. The clip doesn’t fit on the tank so I had to tape it up. The filter has to be at an exact angle for the filter to so somewhat quiet. I also have a larger tank with a Top Fin filter and it barely makes a noise.

Rated 5 out of 5 by from Nice! Quiet, and easy to set up. Works beautifully Not sure what everyone else with bad ratings was talking about. The pump is quiet enough. Cute lit tank.

Rated 5 out of 5 by from Quiet and good so far Set mine up yesterday and it is quiet and working properly, maybe it’s a new design since some people seem to hate it. I just wish with my bubbling led there was a way to turn off the led lights and leave the bubbles on.

Rated 1 out of 5 by from Nice filter. But so noisy for a small pump. The filter looks great and the flow is perfect for small tank. But the little pump attached to the Whisper 3i is so noisy. There's a huge vibration sound so i got to stop the pump every night before sleeping... Not if my pump is defective or its always like that :S

Rated 4 out of 5 by from Whisper 40i doing a great job Super quiet, easy to set up and its keeping my tank crystal clear. The only difficulty is I keep the water level high in the tank so the clip did not keep the filter high enough. The suction cups aren't the easiest to install (I had to use a small screwdriver to gently persuade them into the holes) but they hold on well.

Rated 1 out of 5 by from Quit working after a couple of hours I bought the 10i as a temp filter till i got a better one a couple of days ago and put it in today and it worked when i plug it in,when I went to check on it ,it wasn't running .Tried plugin it into different outlets still nothing.Sad thing is i can't return it after its been in my tank.Wasted 16 dollars for a filter that doesn't work.
