Rated 5 out of 5 by from Works extremely well I used to own this power filter in the past for my 10 gallon aquarium the price was very reasonable where I had purchased it which was at my local Walmart. It was quiet simple straightforward and did exactly as it was designed to do. Overall to me it's a classic and I highly recommend it.

Rated 5 out of 5 by from Noisy? I have never had an issue with noise with any of my whisper filters and I have several tanks. If you look at the construction, the only way it could make noise is if someone is using it improperly, there are no parts that rub on one another.

Rated 5 out of 5 by from Long lasting! I came to this site simply to look up the filters, but when I saw the negative ratings I just could not leave without leaving a comment. I have had a 10 Gal (since 1995) and a 20 Gal (since 2006) Whisper filter each, and they are still going strong. I have had to replace the impeller in each once. Other than that, they have been maintenance free.

Rated 4 out of 5 by from Excellent filter for aquariums under 100 Gals. My Whisper 60 has excellent filtering properties and has the appropriate suction to handle the job. I have had aquariums for over 50 years -- from 5 gal to LARGE -- and my current tank is 55 Gal. I have used inside filters (corner and under-gravel) and outside filters, as well as canister filters, and the Whisper 60 is perfect for my 55 Gal. setup. Regarding complaints about noise, bubbles, etc; i believe (based upon past experience) such problems are usually caused because the filter tube pickup was too close to the sand which allowed sand to be picked up and the sand interfered with the impellers. Regarding noise, if the pickup tubes are NOT properly secured and the connections not tight, then air will infiltrate the suction tubes and create bubbles and produce noise. IF the tubes are connected property and are tight, IF the impeller is properly installed, and IF the pick-up tubes are kept away from the sand, this filter is very quite!! I suspect any reviews stating noise problems are probably due to improper assembly or installation. I have 2 Whisper 60 filters in use., Both of my Whisper 60 filters are quiet and problem free! A great filter and well worth the investment.

Rated 1 out of 5 by from Ok product, don't fall for the bogus $10 rebate Works well enough, but don't fall for the "up to $10" rebate sticker. It's only $5 when, because the higher amount only applies to a product that isn't found anywhere I can see -- stores, Tetra website, Amazon, etc.

Rated 1 out of 5 by from More like "hurricane" filter I'm not sure about the whisper aspect of this filter. I have been raising tropical fish for over 45 years and have used just about every type filter available. This filter is by far the noisiest filter I have ever encountered. How noisy is it? It's loud enough that I couldn't hear the running washing machine in the laundry room next to our family room where the tank is located. Again, having considerable experience with tanks and filters I tried all the "tricks" of the trade and nothing quiets the Whisper power Filter 60. Needless to say the filter is going back to the retailer.

Should the filter water be running at all times? I set mine up and at first the water was running bout now thing is happening. 

Asked by: gdenesis682
Yes, it should be operating constantly, 24/7. Make sure your tank is filled with water, pull out the intake tube and check the impeller for debris, and then re-seat it firmly and pour more water into the filter. Call 1-800-526-0650 if you need more help. BREX

I need to replace an older model whisper 2 power filter and can't seem to find the one that is the same size... Kot Sure if it would be the 30 or 40... I need one that has the exact same measurements as the old whisper 2. Thanks!

Asked by: Ric Flair
That would be the same as the Whisper 40. Exact dimensions are slightly different, but not by much. BREX

My granddaughter received a 3 gallon 360 View Aqua Culture aquarium, what power filter goes with it. It takes a XS filter?

Asked by: LKC1
That kit is not our product, so the filter is not ours either, although we do furnish that manufacturer with the cartridges. The XS replacement cartridge is available at Amazon, Walmart.com and Walmart stores. BREX

If I’m not mistaken, I put 3 of the large filter cartridges in my PF-20? Just picked it up for my boys the other day and do I have to buy any other filter cartridges besides the 3 pack ready to go ones?

Asked by: Ricky 488
The Large size is the correct size, but it uses only one at a time. It also has a foam filter that goes into it. These come with it initially, and the foam filter you keep, don't toss it, unless it wears out. BREX

This filter is a bit strong for my tank, are there settings to slow it down? 

Asked by: Hummingbird
Thank you for asking! There is not a flow control on the filter. You could put a sponge pre-filter over the intake to slow the flow some. For more help please call Tetra at 1-800-526-0650.
