Aqua-Tech Ultra Quiet Power Filter is your answer to keeping aquarium water pristine without the fuss. Our complete 3-stage filtration system provides coarse floss to remove large particles from aquarium water; carbon filtration to remove odors, discoloration and impurities; and Bio-Foam biological filtration to remove toxic ammonia and nitrites on contact. To ensure crystal-clear aquarium water, change the filter cartridge once a month, as carbon deactivates with use.Even with a decoupled motor running at less than 40 dB, this filter makes no sacrifices when it comes to power. Our impeller and motor assembly designed for efficient power usage filters a whopping 200 gallons per hour – completely filtering 20- to 40-gallon aquariums 5 times per hour. This filter uses the Aqua-Tech EZ Change #3 Filter Cartridge with Premium Activated Carbon. Aqua-Tech Filter Cartridges trap dirt, remove impurities and deliver maximum water-to-carbon contact to make your aquarium water sparkle. Designed to fit standard aquarium hoods and canopies, the Aqua-Tech Ultra Quiet Power Filter is a sophisticated filtering process made easy. Whatever your individual needs, Aqua-Tech products help make aquarium maintenance simple for a clean and beautiful aquatic environment.

    Cleaning is important
    I’ve used this particular aquarium filter for years and when it stopped working, I bought another to replace it. This next one didn’t last very long at all. Thinking I had just received a ‘lemon’, I ordered another. Again, it worked great at first, but only worked for a couple of months before the water flow was almost nonexistent. I followed the instructions and cleaned the impeller. Still, nothing. I decided that I had to be missing something so I began examining the impeller housing a little more closely. I found that not only does the impeller area collect impurities, but the tube area above the impeller does also. There are slits in the plastic tube above the impeller housing where things can collect and block the flow of water. After removing this blockage, the filter worked like new! So, the problem really isn’t with the filter. The problem is that the instructions only go so far as to tell you to clean the impeller, but not the area above it. As a side note…I use polyester fiberfill in a small corner filter and it was those tiny fibers that I found to be wrapped up in the impeller and also blocking the slits. It’s a great filter if cleaned properly!

    Terrible!
    This filter is the worst! It’s noisy and difficult to clean. For the first year I had a rubber band holding it together. Then I needed a wadded up paper towel between the wall and filter to quell the racket it made. Then even the paper towel didn’t work. It hummed and rattled so loud I could hear it downstairs with the door closed! Today after not even two years since purchasing it I pitched it and got another brand. I’m 72 years old and have had aquariums since I was 5. Never had problems with any filter and they all lasted several years. No need for two filter pads for a ten gallon aquarium. If you do water changes once a month or so and don’t over feed you won’t need two filter pads. Just another way to rip you off. If you decide to purchase this filter only use one filter.

    Very disappointed in noise level
    After trying 3 different filters on my 36 gallon tank, I came across this 30-60 gallon Aqua Tech with amazing reviews. Even with it being a little more expensive than I have paid in the past, I thought I had found what I was looking for. Pkg came on time, very easy set up, put it in the tank and plugged it in….the hum was so much louder than I ever thought it would be. I even checked the impeller as the directions call for, made sure it was set properly on the tank, filled the tank to the very top and it still has a very loud hum. It works like a charm – suggestions on how to make it quieter? Hate to waste this money and go back to my Whisper, but I may have to.

    Very happy with the operation and its long life.
    This is the second filter of this same brand and size. I finally replaced the old filter after 4 years that was still running but really dirty. This one should run just as long. Easy to replace filters and clean. Not loud like others

    Broke within less than 3 months of use
    Worked great at first. Within a month it started acting up. It has been less than three months and it totally stopped working. It is clean and not jammed. Very disappointed, I do not recommend

    Después de 2 filtros anteriores que no duraron ni un año, encontré este. Es un excelente filtro, de muy fácil ensamble e instalación y los reemplazos se consiguen muy fácilmente. Mantiene el agua de mi acuario ( 30L ) en perfectas condiciones por meses!
