Tetra - Whisper 40 Power Filter 20-40gal

i recently replaced all my pumps {5}on my fish tanks, BIG MISSTAKE......these are the noiseiest ones that i have ever had in my life.....wish that i had not done it............

Harriet,
Absolutely quiet!!
You must be doing something wrong.
Make sure the impeller is seated properly in the motor, and keep the level of water in tank to top.

I used Whisper power filters for many years and was able to adjust carbon and use ammo chips if I chose. Once I got the hang of it, I never had a problem. Recently started my aquarium up again and could not by Whisper locally. I have tried 3 different major brands and each was its own type of disaster.

I've been using Whisper filters for over 20 years. Just bought the newly designed Power Filter 40, but it will not fit on the back of my aquarium like the previous filter did. I use a full hood with 48" fluorescent tube light, and it will not fit over the lip in the back.

Worked great for me as additional filter on a large tank. Its not silent but very noisy. Easy Yuri clean and set up

I have owned every size of these Power Filters Whisper has and have loved each one. They are simple, efficient, quality, quiet and I've had clean clear Aquariums largely due to the help of these Filters. BUY THEM!

MY BIRDS CANT STAND IT I JUST BROUGHT IT TRYING TO FIGURE IT OUT ALL NIGHT. NOT WORTH MY TIME OR DOLLARS. BE EASY.
