Tetra Whisper EX: The Quiet, Multi-Stage Aquarium Filter for a Peaceful Environment

LeafaRae: Purchased this for a lidless, 10 gal tank. Works great, filters water. Bigger than expected. Theres not really any room to add additional filter media to filter compartment. Not very loud but, is the loudest out of the 4 filters i own. Nice flow but its not adjustable. 'net end' of intake siphon tubing is an elongated bulb shape thats too large to fit small 'filter intake' sponges, tiny fry would easily pass thru openings to impeller. Minimum Water Level needed for filter is 'too high' to keep water line lower for critters such as mystery snails.

Its not a bad product. It works for what it was intended. Ive always trusted tetra products.

Nick Ambio: I bought two of these for my 125 gal tank and they work great. Water is always clear and they aren’t too loud. I’ve had them for a year now and they’re still kicking. Every once in a while one will randomly get a little loud but cleaning the little magnetic propellor usually solves that problem. Occasionally when the water gets low they will be much louder too but that’s always an easy fix.

Amazon Customer: Do not buy this! It is cheaply made and makes a lot of noise and mine does not even turn back on half the time when it is unplugged to do a water change! I have been back and forth with Tetra over this cheap 30$ filter and have gotten no where. They expect the product to be mailed back for insepction before replacing, um what am I supposed to use in my tank while they do there inspection, go buy a whole new filter while they figure it out then get this one back and have 2. Probably should have a back up anyway but what a hassle and a terrible warranty procedure. The company should be doing what Amazon does and mail you a new product and give you so much time to return the old one or be charged for it upon not returning the failed product. I do not recomend this filter and the customer service is terrible. I would give 0 stars if it was an option. And also they should be covering the shipping cost! I will just buy a new one that is a better brand and never give Tetra mu business again, I would stick woth Hygger or Aqueon! Way better products!

JMJM: The media could not be loaded.  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,...

Alexandra: El filtro llego a tiempo y bien empaquetado, el ruido que hace es minimo, en mi caso solo alcanzo a escuchar la cascada de agua que cae del filtro, el filtro pasado tambien era tetra, puede ser que me acostumbre al ruido, pero no es nada molesto. Es muy facil de armar y viene con instructivo por si las dudas, aparte trae un tubo expansor para alargar el filtro dependiendo de la profundidad del tanque. Mi pez y yo estamos encantados con el !

Amazon Customer: We used a "M..." brand for 4-5 years--it was always a problem, breaking down, needing to be reset, and very very noisy. Over that time I got three, but each failed. It made having a fish tank a BIG constant chore. I din't know how the fish could stand the grinding noise from the mechanism, as it certainly bothered us.
Finally bought the "Whisper EX20" and what a blessing from the start, and lasting.
I don't write reviews, but I wanted to support this company and product as it has made areal difference in our lives, as with two kids and dog and being a single parent--we are busy enough as it is.
It is QUIET, very quiet as I only slightly hear the water(fall) trickling. The tank is really clean (for once), and stays that way for long periods. And the filter is very easy to remove, clean and replace. I just spray it with the lawn hose to clean it.
I read some review about the thin construction and hatch to the filter--my experience is that overall it works well, doesn't need to be any stronger as it functions sas needed. And, that may have helped keep the price down, which I appreciated.
I definitely recommend this product.

Sandra Margret: I rescued two goldfish that were being auctioned off at a Jack and Jill -- otherwise, someone claimed they would swallow them! $14 dollars later I came home with two sad looking fish in a plastic bag. Realizing that I had an old tank stored in the garage, I quickly gave the goldfish a home. They grew bigger and bigger so I bought a larger tank, various assorted plants and the best food that money could buy. I needed a larger filter and bought this. So lovely. It keeps the tank very clean and it while it's not entirely whisper quiet, I like the sound. More importantly, I can buy the very economical un-assembled bio-bags which makes filter changes incredibly economical and easy. My fish are very happy and so am I.

Charles: The media could not be loaded.  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...
