REVIEWS, PRODUCT
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.

Not happy
Spent over $20 on this filter for my 20 gallon long tank it makes a loud vibrating noise and gurgles water in the back part! It’s so loud I can hear it loudly across my room I can only imagine how annoyed my poor fish must be.

Works Great
Lots of negative reviews here, so I thought I’d chime in. This filter works great for my standard 10 gallon aquarium set-up. My last off-brand filter stopped working after 2 weeks and my aquarium started getting cloudy. I popped this filter in and the water was clear again within the hour. Time will tell, but for the purpose, this filter works fine. Can’t beat the price. It’s a little bigger than I’d like aesthetically, but if it works and my fish stay healthy, I can’t complain!

3i not flowing water in less than a month
Bought a glo-fish cube aquarium from Tetra and it came with the 3i bubler filter. It worked fine for 29 days and quit flowing water. Replaced the filter and still no flow through the filter. Bubling is functioning just fine but now without filtration, the water is beginning to become cloudy.

So far the Whisper 40i has been perfect
I bought several of these for my smaller turtle tanks. Wrapping the bottom with polyester media prolongs need to clean filter and protects the impeller from clogging. I recommend this particularly for Turtle tanks 20 gallon or less.

WHISPER FILTER
Just installed the whisper 3 and not impressed. It doesn't fit right in my tank I can not put the lid on, the motor has to be higher than the water level and the plug in has to hang ???. It just spits out water from the spout but the clear bubble part is going strong. Its not designed for my tank and I will find a more suitable one then return this one.

Why does it have holes and no suction cups?
Filter is quiet and would work great, but it comes with no sucktion cups and has holes in the back!? The water leaks out the back and this doesn't work with my tank setup (clip doesn't fit on my tank style).

Extremely Annoyed
I recently purchased this filter. The box said it came with suction cups as well as the clip. Upon opening the box I realized only the clip came with the filter. I am unable to use the clip since my aquarium has a lip on the top. I contacted customer service and they basically said “too bad” buy suction cups from our website. There is no way I am paying 4.20$ for suction cups and 13$ in shipping.

Great until it's not
Purchased two filters for my tanks. The large filter is going strong, but the smaller one just pooped out this week. It was running great, quietly, and reliably for less than a month before it simply stopped. I am super bummed about it, because I quite like the filter for its aesthetics and functionality! Had it not quit, then it would get a solid FINE STARS without hesitation. I suppose this is simply a "buyer beware" tale. They are wonderful while operational, but that period of time might be limited. [saddest face]

Hello, I've had a whisper 2-10i for a little over a month and today it started vibrating loudly. I looked up how to check the impeller but there is nothing blocking it, and water is flowing through it. I'm not sure what I should do. Please help.
Asked by: tsarter
Vibrating can be due to the hanger or suction cup not being positioned properly (the filter can get knocked by a turtle or large fish or while the owner is feeding etc) and may need adjusting. Also, we always recommend swabbing out the motor in case there is some fine debris in it that you cannot see easily. Q tips work well as does the corner of a paper towel. Also, if you have an air stone in the tank, make sure it is at the other end. BREX

Is this filter submersible? As in, part of the cord is in the tank as well?
Asked by: Loni
If you have the 4i, 10i, 20i or 40i, yes it is submersible including part of the cord. BREX

I was given a Tetra Floating Starter Kit 1.5 Gallon Cube. There was no Quick Start up manual.Can't find out how the Filter goes together
Asked by: Allyoop
Sorry to hear the manual was missing. The instructions for the internal filters are on the product page on our site. We will try to email you the guide for the tank, however. You may also email petsupport@spectrumbrands.com if you don't receive an email. BREX

For the 10i filter how many time an hour does it filter a 10 gal tank??
Asked by: Tiff9
The flow rate is 90 gph, so 9 times per hour. BREX

I bought the Tetra Floating Starter Kit and the filtration has worked fine, but yesterday it was barely flowing. Today it is flowing so hard I can see the plants moving in the water and my fish has been hiding all day. What can I do?
Asked by: AJ811
That filter does not have a flow control, but you can insert a flow control valve in line about 8 inches from the air pump to help reduce the flow. When the flow is slow, clean out the hole in the bottom of the filter body and replace the cartridge. BREX
