Tetra Whisper Power Filter EX30

I purchased 2 of the Whisper EX30 units for my 33 gallon long tank. Both work flawlessly and quietly. I even took a short video of them. Finally the air circulation system in the building shut off so I could tape this (Very rare, building owner doesn't like people suffocating in the building and dying I guess), both of these units run quietly enough together that the little bubbler is louder then them. The video is filmed in dead silence in the middle of the night. TV easily drowns these out. They do make a little hum, not a big deal, they all hum a little. These truly are whispers, if yours isn't, talk to someone about it and get it replaced, you have a defective unit. Neither has given me any trouble, both work the same and are very reliable. You can also see the water is crystal clear, my water is never any worse then it is in the video, even right before a bi-monthly water change. Only thing that bothered me, not enough to take away a star, was it is a little snug on the tank, good in some cases, I just like a bit of play because down the road if they ever do start vibrating or such, I could put a thin foam pad between them and the tank and loud pumps go quiet then. Did that with the Aqua-Tech I had prior to these because it screamed like a banshee right outta the box. Seriously impressed with these units though, and fitting snugly is probably a good thing. And by snug I mean, it fits like a glove, no forcing it on or anything, fits right down as it should, but has no play. Like it was machined to fit (On my tank anyhow). PS - Disappointed with the FEDEX guy though, slacker entered delivery attempt when none was made since I was here the whole time, gate unlocked and open. No door tag provided, secretary and surveillance cams saw no sign of him anywhere that day, didn't even drive past. Had to pick this up 2 days later and talked to manager. Disciplinary action took place before I had even left, glad I wasn't that guy, they were really tearing a strip off him.

I just assembled it and it was really easy! Great design, and no noise at all! The quality is great and functions perfect for my 20 gallon fish tank. Great size. Totally recommend it!

So I bought this filter for my 40 gallon tank. I needed something that I thought would over filter my tank, since I do have a variety of fish stocked. Well the 1st filter arrived BROKEN.... so it was tedious to have to wait an additional week to get the replacement sent out. When it finally arrived, I assembled it & cleaned it before I added it to my tank. Once I had it set up I initially thought it was doing a great job until it wasn't. I noticed that the water started to flow less and less, so my thought was maybe it had collected gunk so I'd clean out the filter to make sure the water could flow through.... nope that wasn't the issue. I checked the tube and made sure it was sitting nice and tight... didn't fix the problem. The water levels were at the correct level, since the filter shows a line where it requires the water level to be. I started to feel very disappointed because the price is pretty steep for such a problematic and flimsy filter. I use tetra filters in my other aquariums (I have a total of 6) which don't cause problems; as long as they're maintenance regularly. Anyways, months went by and I kept experiencing issues, by this time my return window had closed. I went as far as switching the type of media I was using, thinking it would have an easier flow, but nothing worked for me. Eventually by October 2024, the filter just stopped working. I took it apart and checked everything and didn't find anything wrong. I let the impeller sit in water for a few days to see if that was the issue and still nothing. When I would plug it in, it didn't even seem to be on. I gave up and tossed it out. This filter really sucked for me. Maybe I just had bad luck and ended up with a faulty one but I won't be buying this type again. For now I've just kept my tank filtering with the sponge filters and have been shopping around for a different filter. So bottom line, I definitely do not recommend this filter. Buy at your own risk...

I have used 4 different filters in my tall 30 gallon tank. None of them did the job very well—until now. This filter cleared up my very dirty tank in minutes!!! Since we have well water that’s not really good for drinking, we buy and refill 5-gallon jugs. It’s a lot of trouble to replace water when we clean our tank, so I depend heavily on the filter pump. I always use filter-pumps that are rated for 30+ gallon aquariums and change my filters frequently. I use Fritz’s Zyme sludge remover at least once a month. That usually keeps me from having to do a lot of water changes. Since I’ve had my 30 gallon tall aquarium, I’ve had a lot of trouble keeping it clean. The last filter I used was a Marineland Bio-wheel, and it was awful!!! I cleaned my tank today and was shocked by how dirty it was!!!! I vacuumed out 15 gallons of water and couldn’t even see my fish it was so dirty. After I set up this Tetra filter and replaced that water, it primed itself immediately, and my tank was crystal clear in 7 minutes!!!! After replacing the plants and ornaments, I stirred up more sludge. This “bad-boy” of a filter cleaned it up within 60 seconds! I’m looking forward to a long, stress-free, and easier experience with my tank for the foreseeable future. I might buy another one to have as a backup in case this one ever dies. Lol P.S. It is kinda loud but not too bad. I’m going to shim it a little bit. That seems to help a lot with noise.

It’s a good filter easy to clean and cleans my tank effectively

Too loud

Me gustó el precio, su material, el plástico es fuerte, el consumo de energia. No me gusto, que no tiene regulador de flujo. Lo compre en 252.40 pesos mexicanos el 14 de nov de 2020, por amazon prime. En sus características indica erróneamente las médicas de este, ya qué indica: de largo 15.39 cms., ancho 14.12 cms., y profundidad 23.34 cms. Y sus medidas exactas son: largo 14.56 cms, ancho 13.8 cms y profundidad 27 cms desde la salida del agua. Busque en la página de Amazon y nunca encontré cuanto consume de energia, consume 4.8 watts sin saturar y saturado 5 watts, el largo del cable de alimentación es de 1.70 cms. No hace mucho ruido si lo limpias siguiendo las instrucciones para sacar la propela del manual. Me funcionó bien con un acuario de 52 litros pues el flujo no es muy fuerte, dimensiones de mi acuario 50 largo 26 ancho y 40 de alto, todos centímetros. Lo compré en 252.40 pesos mexicanos y era el más económica en ese momento por amazon Prime de México.

I bought two of them , the items in the package are scattered, when it was installed, it made a loud sound and it worked for five minutes only and then stopped working, very bad, not worth the money, I cannot return them, I am out of the country now, not recommended at all

Works well. Keeps water clear. Very quiet like name suggests. Install was fast and simple.

Es un excelente producto, muy practico y eficiente, fácil instalación y limpieza, producto 100% recomendable, y a un costo excelente
