Tetra Whisper Power Filter EX70

Immediately satisfied. I have a small 20 gallon tank with same filter but it’s maximum rated capacity was 20 gallon same brand /style. It was good but not enough filtration capacity. So I ordered this large 70 gallon capacity. It’s turning the water over through the filter pads in less than an hour scrubbing the water clean. I realized quickly that the small 20 gallon simply wasn’t enough filtering power. I have 5 goldfish so for 20 gallon that’s about maximum population so needed better filtration. I like the easy of filter media change out. No mess no time consuming maintenance. I did consider a couple of canaster filters on Amazon and thought that’s way to time consuming to open it up and rinse out the trays then reload it with 5 different filter media reseal the can and reinstall it. Way too much time involved I recommend this filter to anyone not interested in spending several hours. It’s overkill for my size tank and so it should really to a great job filtering out contaminate. The pickup intake tube goes to the bottom of tank nicely thus drawing water through the filter from area where the most debris are present It is very quite as a plus consideration

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!

I have a hexagonal tank that is tall and thin, meaning filters for rectangular tanks with the same size rating can struggle to create good circulation in the bottom half of the tank. I sized up to the EX 20 to get a higher flow rate. This unit does a great job with both mechanical and biological filtering and my entire tank is turning over much better now. Also, it does not create too much current for my tiny Oranda goldfish, which can be a problem with more powerful filters since they tend to be poor swimmers. My only drawback is that this thing can be LOUD, and I mean LOUD, if it isn't situated exactly so on the back of your tank. There is a small rubber bump on the bottom of the housing that helps balance the back of the unit against the rear glass, but it also creates a vibration point. I ended up sticking a tiny piece of craft felt between the bump and the glass to help dampen the noise, and so far so good. I also put a narrow strip of felt near the top edge of my tank since there is a lip that sometimes vibrated against the housing. Overall, quality seems good/ sturdy construction and it was very easy to set up and clean. UPDATE 1/15/2018: Filter has become unbearably loud, even with my DIY sound dampers. The filter itself is now making a loud rumbling noise that I can't fix. I have tried disassembling and cleaning all of the moving components several times and adjusting how it sits on the tank, but it doesn't help at all. Something is wrong with the powerhead itself and it has become so loud that it interferes with watching TV in the living room and I can hear it when I'm trying to sleep. I've taken it apart and there is nothing visually wrong with the unit, and I use large gravel substrate that could not be sucked into the filter to damage it. I'm outside the return window for amazon, but I did register for the Tetra warranty and I will be returning this thing ASAP. Extremely disappointed that it deteriorated so quickly.

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.

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
