Anyone else have a problem with it backing up? After a few days, the water ends up overflowing and going back out the way it is sucked up-leaving it unfiltered.
Answer by ChewyMar 28, 2018
There are a few ways to troubleshoot your filter. Unplug your Tetra Whisper filter from the outlet and carefully pull it free of the aquarium. Examine the intake strainer and make sure it is not broken or damaged. Carefully remove the intake strainer from the intake tube. Check the tube for debris and clear anything you find. Pour the water out of the back of the filter. Pull out the old filter and replace it with a fresh new one, then carefully place the filter back on your aquarium. Fill the back of the filter up with water that is roughly the same temperature as the water in the tank. After the back reservoir is filled to the top, plug the filter in and listen for the motor. After a couple seconds the motor should come on and you should see water begin to flow. If water is not flowing the motor may be damaged.

Is this a gentle water flow? I want to use it for a betta tank, but I know they don't like hard flowing water.
Answer by ChewyNov 23, 2019
This filter would be suitable for a betta in a 10-15 gallon tank, however, pet parents of betta fish that have used this tank in smaller gallon set-ups have reported too much movement in the water. Tetra recommends that fish parents with smaller betta set-ups opt for the Tetra Whisper 2 -10 Gallon Depth Power Filter instead.

how often should you replace filter media ?
Answer by ChewyMay 22, 2019
When water flows excessively from the Wonder Tube Chamber into the aquarium, it is time to change the Bio-Bag. The Bio-Bag should be changed once per month to prevent backflow and avoid filtration problems resulting from a clogged Bio-Bag.

About how loud is this filter when in the tank?
Answer by ChewyAug 06, 2019
The Tetra Whisper Power Filter is made with silence in mind. Pet parents have reported this filter to be as quiet as a running ceiling fan.

Much more tha a "whisper"

This filter is much to noisy for me. I've tried several times to "re-seat" the impeller but it's made no improvement. I'll be replacing it.

So loud & quit workinb

This filter worked for less than 3 months before it quit entirely. The name "whisper" should be "loud buzz". The sound was so loud, I could hear it in my bedroom! Not worth even the small price for the inconvenience.

Waste of Money

Bought on January 1st, this filter was extremely loud. Not good for a frog. Anway, it totally quit working on February 11th. I pulled it out, bought an Aqueon filter, and it is a night and day difference. There is barely an audible sound. Do not waste your money on this unit!!!

Loudest filter

Filter is unbearably loud. Vibrates the fish tank, I would feel bad for the fish having to live in a vibrating tank and the noise on top of it. Threw it out immediately.

I got this for my 10 gal aquarium, and it's possibly the worst filter I've ever used. I had previously purchased a smaller Tetra Whisper for my 5 gal aquarium, and it lived up to the name. This one has NO flow control, and the "whisper" is more like a freight train in my living room. I do not recommend.

The loudest thing ever

I purchased this for my 10 gallon tank. I have a smaller tank with a hang on the back filter and I thought it will be very similar, but boy I was so wrong! I tried uninstalling and putting back together several times and there is no way I can have the noise all day. I did not spent a lot of money but I will replace this for anything else. It sounds like an airplane is in the room. Will not recommend this filter.

Guppy Whirlpool

Well it was working great until it spun my fish into a mini current and sent them flying against the front of the tank. A little too powerful for a 2.5 tank. I can’t tell if the fish liked it or if they were mad because they kept going back into the whirlpool. I can’t use it for this small tank but I can definitely see this working well for a 5 gallon or 10 gallon.
