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.

Rated 5 out of 5 by from Excellent Filter I bought a Whisper Power 30 over 10 yrs ago for my 20 gallon tropical tank. My water was crystal clear, the filter quiet and the fish always healthy. It's easy to maintain and one of the best features of the filter is the ability to adjust the water flow. If not for the impeller wearing out and the cost to replace it being 1/3 the price of a new one it would still be in operation. So, I bought a new one.

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.

Hi, since I changed my filter in my Whisper PF10 ( first time ) it has become more noisy than before. Why would that be?

Asked by: Britchick
You may have jostled the intake tube out of position just a bit or it may have pulled in some debris. Check the impeller, intake tube and down in the motor, then re-seat the intake tube firmly. Call 1-800-526-0650 if you need additional help. BREX

Regarding the Tetra PF10 filter. The Bio-Bag filter medium is in the "V" slot in the housing and the foam grid fits forward of the Bio-Bag. I am wondering what the wide slots either side of the top of the waterfall is for ? Is there a piece I'm missing ?

Asked by: Rialbo
The "V" slots are the wide slots at the top of the waterfall, about an inch back from it. This is where the cartridge goes. I'm not sure where you have inserted the cartridge. BREX

Why is the Tetra whisper power filter leaking 

Asked by: 4gayle
Unplug it and remove it from the tank, take everything out of it, then turn it upside down to check the motor. Look to see if there is a red rubber ring that is sticking out. If so, this is your o ring and it is pinched. Pull the motor out, line the o ring up properly and re-insert the motor. If the o ring is not sticking out, remove the motor and make sure it is not missing. Also check for hairline cracks in the neck of the motor or in the filter body. Call 1-800-526-0650 for more assistance. BREX

Will this fit the tetra 16" x 8" Hood - 1 Watt - (1 Module w/ 3 LEDs)?

Asked by: burne4c
No, this filter is way too big for a 5 gallon tank, which is what that hood fits. The Whisper 10 would fit it though. BREX

What replaces the power filter 4. I cut my lid to fit it and would like to find the same or replacement for it

Asked by: paisley
We do not have a filter close to that any longer. The Whisper 60 is the closest in flow rate, the Whisper 40 is the closest in size, but a good bit smaller. BREX
