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.
Whisper® Internal Aquarium Power Filters is rated 3.1 out of 5 by 63.
Rated 1 out of 5 by from Dissapointing My son wanted a turtle so I went out and got the turtle and this filter system. At first it seemed very good. The water was clear but by the second day, the water was murky and remains so. stays murky. It is not filtering like it should. I've seen others turtle owners who use this system and the water stays clear. I don't know what the problem is.

Rated 4 out of 5 by from Suction cups I bought a tetra whisper filter from Walmart last week and as I was installing, I saw that it didn't have suction cups. So I thought that someone must have taken them. Then, I went to Walmart to return it for a new box and there weren't suction cups AGAIN. So I figured it must not have suction cups and so I've been trying to glue on suction cups and my tetra filter keeps tilting over. I looked at the reviews online and theirs came with suction cups. Is this a manufacture fault or walmart?

Rated 1 out of 5 by from Loud and noisy I purchased this a few days ago and since day 1 it has been making a terrible grinding noise! It is extremely irritating since my last Tetra Filter started doing this in just a few months of use. I will be returning it ASAP.

Rated 2 out of 5 by from Works as described. It is quiet as it says. Cannot use the clip provided. Doesn't allow for the hood/light to sit properly on the top of the tank. Using 2nd suction cup instead of the clip, just had to drop level of water a bit more than I like. Instructions were a little vague on how the filter and the scrubber are inserted but I think they are in correctly. Been running for a few hours now and the water is already crossing over the top of the filter cartridge. That shouldn't be happening already especially being new. Other the few problems, it works as described. Why I give it a Fair rating.

Rated 1 out of 5 by from Bad design. There is a basic design flaw in the Whisper 10i. Not all the water pushes to the front and if one is not careful water will run out and over the clip that holds the filter in place. The water runs over the clip and onto the floor. I have 3 of the filters and at one time or another each of them has overflowed over the clip. I will look for a better filter for a small tank.

Rated 1 out of 5 by from Terrible The filter stopped working and I was unaware of it. I came home my house was full of smoke. All of my fish were dead.

Rated 3 out of 5 by from This filler and my betta I just bought the whisper 10i filter and I like it so far I set it up and it is working well but the water current is a little to strong for my veil betta fish and he is having a hard time finding somewhere to rest being I don't have much things for him rest on but I guess with this new filter I will have to get more
