  • It would be more helpful if you compared the filters by how well they work, longevity, cost and availability of media, and noise. I have used Hagen AquaClear 70’s for years, and they filter well,
    but I just can’t stand the noise any longer. I want to try another brand.

  • Hi Hank

    Thanks for the feedback. Unfortunately, the factors you list in regards to comparison are extremely subjective. Depending on how someone uses a filter, what someone considers “loud” or not, and even the cost can vary or change. Because of the subjective nature, we won’t be able to add those categories.

    I was hoping to suggest an alternative hang-on power filter for you, but our Live Deliveries Manager, John, said the AquaClear 70 is no louder than any other hang-on filters on the market. If the water level is appropriate in your aquarium, the filter will barely make any sound. If your water level is low, then the filter will cause splashes. A completely different route to go would be a canister filter. These make almost no noise whatsoever, as they are located under the stand and the intake/outlet are well beneath the surface of the water. We have 2 of the largest and highest water flow canister filters on our company 265 gallon aquarium, and there is no noise while each of the filters are pumping about 600 – 700 gallons per hour.

    If you have any questions, please feel free to contact us!

    Thanks –

  • The noise problem has bothered me for a while. I have used many different hang on filters. I now use the Fluval C4. It is very quiet. The quietest one I’ve used is the Aqueon Quiet Flow. They make almost no noise. I now have one on my 10gal. Planted Shrimp tank in my bedroom. The worse I’ve used is the Marineland Penguin. The impeller makes a lot of noise.

  • i have a 49 bow tank and a 30gal long tank,i”ve had them for years and i have the aqua clear 110 and the aqua 70 on the ,2 tanks and i love them!yes some times they make a little noise ,exspeacail when the water may be down 2in .however i have a muscal deises so i some times miss a water change and because the filters are so good ,my water and fish and yes plants are healthy! i have 1 oscar and 3 blood parrots and a plecostomus in 1 tank of course the biggest 1 and the fish are about the size of my fist and pleco is about 11 inch and the other tank has african cichlids abot 8 and there pretty big and colorful! so i love my filters and i put an extra air pump in there to !so way to go! i do have a question i have a guardian 300 watt sub. water heater and it has some rust build up and doesnt keep the tank as warm as it should ,does anyone know how to contact the co so i can get it replaced ,cause it say lifetime warranty and i’ve had it about 2 years? thanks

  • I am not familiar with the guardian heater, as it is not a product we sell. I suggest you contact the manufacturer of the product to see about making a claim on their warranty.

  • […] Here is a chart on how much room different HOB filters need. Wow, my googlefu is strong tonight! http://blog.petsolutions.com/blog/20…power-filters/ __________________ […]

  • A chart including what filters have a flow control would be great. I won't buy unless I can turn down return for feeding.

  • Great suggestion, Brian! I'll get the table updated as soon as our Fish Tech indicates which filters have that feature.

    Thanks –

  • Hallo
    It would be nice if this charts had a column with the "max inches rim/edge" that these HOB could hang on …..

    kind regards Rikke

  • i am trying to find a filter to work with my SunSun CUV-303 UV filter tube…it worked great with a small power head built into the hood of my small but tall hex tank (15 litres)… Now I have a 14″/36cm cube tank, the little Aqua One filter I bought is not strong enough to pull water through the extra UV section, it won’t prime/ start up.
    I need to know the internal and external diameter at the base of the U-tube intake into the filter on the AquaClear 20, which I am looking at to replace the inefficient AquaOne…could someone who has one, measure it for me? It’s very difficult to match up the two devices…the UV tube that fits into a filter is 15.5mm internal diameter internally and 16.5 mm diameter internally, walls a 0.5mm thickness, as best I can measure them. There are adapters for bigger filter inlet tube connectors, but not smaller ones…I can jury-rig a bit with a bit of clear plastic hose, but only as much as it will stretch when heated, which is maybe 2 mm…
    Thank you so much for any measurements and suggestions 🙂

  • Oops, that was 15.5mm internally and 16.5mm externally….
