Questions & Answers

20 Customer Questions

Could I use this filter for my 20 gallon tank or would the intake be too long?
Answer by ChewyOct 17, 2017
The Tetra Whisper EX Power Filter is available for 20-30 gallon tanks and would absolutely work.

what size replacement filters work
Answer by ChewyDec 09, 2021
We carry the "Tetra Whisper Carbon Medium Filter Media" and "Tetra Whisper Carbon Large Filter Media". The 10-20 gallon size filter would take a Medium filter, and all larger units would be compatible with the Large filters.

How would this fliter be with frogs?
Answer by ChewyOct 24, 2022
This filter can be used with frogs as long as the frogs are aquatic and kept in a tank that is filled to the top with water. It has a submersible motor that must be in water at all times. It will not work in shallow water.

How long is the intake tube?
Answer by ChewyOct 14, 2020
Tetra Whisper EX Aquarium Power Filter has a submersible motor in the water with several short extensions about 3 inches each in length so you can make it as long or as short as you want. Depending on the model size, you can get between 2 and 4 of these short pieces. Each filter comes with a strainer which is 5 to 6 inches long.

It works but not quiet for long

I already owned this filter and was buying a replacement because the old one wasn't so quiet anymore. It's always prudent to have a back-up unit, as well. Installed this filter and it was beautifully quiet...for about 24 hours. These do the job but they do have an annoying hum that is not tied to vibration against the tank.

Stopped working after 3 months

Ordered January, and by early April it already stopped working. I read the reviews, hoping it may be a one-off that some didn’t work, but no. The filter is simply not quality and doesn’t hold up at all.

Best Filter On Many Levels

I've enjoyed tropical fish since I was a kid and have gone though several filters along the way. Preference always given to HOB filters. The Tetra EX Whisper series outclasses them all in terms of cost, ease of use, durability, design ( particularly placing the enclosed motor within the water column ) which, in effect, makes this the quietest HOB filter in the marketplace, bar none. I have five of these at work, replacing larger Emperors and others. The media space also allows one to customize what media you actually prefer. I'm not particularly keen on review writing but the superiority of this unit was just too compelling.

Good job filtering, but noisy

Title says it all. I installed on a 40 gallon tank that's in our bedroom. It keeps the water crystal clear, but it is definitely not "whisper" quiet! Today, I ordered another eheim canister filter to replace it because I can't deal with the motor noise while trying to sleep. We have an eheim canister on the other tank in our bedroom and it is much quieter. I'm going to use the tetra whisper on our quarantine tank that's in another room. This filter would be great in a room where the extra noise isn't a problem.

It’s a really nice filter

I really like this filter it’s easy to use and runs nice the only thing would be that pressure can put ur fish at unease for a while

Stopped working after a month

Just stopped working out of no where. Walked past the tank one day and realized it wasn’t making any noises. I just bought it a month ago. Not recommended for a 50 gallon tank.

Worked fine until it stopped working

Worked great until it randomly stopped working today. I unplugged it for every water change and set it up properly.
