Aqueon QuietFlow E Internal Aquarium Fish Tank Power Filter For Up To 40 Gallon Aquariums

I had 2 Zilla filters for my large turtle tank (left side of pic) They were loud and "burped" a lot.I've now replaced both of them for 2 of these filters. They run much better. Same flow and filter cartridge. Much quieter. I also like the sponge filter that is added.

Well, the title says it all, really. The filter is about 10.5" top to bottom, and the only way to make it really quiet is to mount it using the 4-suction-cup option (rather than hanging on 2 clips - the other option. This means the entire 10" is visible in your tank. I like to over-filter a bit, so this is actually in a 30-gallon tank, but rectangular, so not really so much smaller than a 40 size.Tried mounting it on the clips, but this way it spills its water out in a waterfall, and I am used to an internal filter with very little sound at all.When mounting inside using the suction cups, I have to watch the water level very carefully, or the filter is completely submerged and it looks as if incoming unfilitered water might overflow out the back of the filter tank, over the foam and the carbon filters. Too bad, because now my aquarium is not fillable to the top - there is an inch of open glass showing at he top frame.Quiet, tho, and the filtration looks good for the first two weeks.Note: >>>> the dimensions are very close to : 10.5 top-bottom...4.0 front-back...6.0 side-side, which would be about right for a hang-on-the-back filter, but big, big for inside-the-tank....PS: comes with a couple of $2 coupons for Aqeon fish food and supplies...did not look too closely at those.

A quick series of power outages fried my turtle's filter and I bought this one as a replacement. It does a great job at keeping the water clear and was a good value. I knocked off a star because it is a little noisier than other filters I've had and seems to use more water power than some others. Still, I'm pleased with it and will probably buy another when this one gives out.

I bought this for its ability to function in shallow water. I have an African Sideneck Turtle who does not like deep water. She prefers 2-3inches if water and that’s that. She is in a 40g tank with only 5-10g of water in it. I could have probably gotten away with the 20g filter, but hey with the amount of Easter turtles make... me bigger the better. The water is crystal clear at all times. I typically do a water change every 2 weeks and this filter does not disappoint. I recommend not going below 3 inches of water depth because it will make a funny noise indicating that it is struggling. Because I’m he water is so low and this thing is massive, it does make a loud waterfall sound that will disturb some people but it puts me to sleep. It takes up a Lot of real estate in the tank, but my turtle loves it and often sits under the waterfall :)

It really stopped working the one day after my return window. So it did not last a month. When I installed the filter it was loud. Which my first one was not but I still did not return it. One morning woke up to a non working filter. It would suction but no water would come out. I also had changed the filter inside and turned it on again. Still did not work. Do not get it.

Bought this to replace a canister filter that was very difficult to maintain. The pros of this unit are that set up is a breeze and filtration is amazing. I have a very messy water turtle and this cleared the tank very well over about 24 hours. The water flow from the top is good. It gives the turtle a good current which she needs because she is a little pudgy and I want her to have to work for her food. It nicely breaks the surface tension of the water, something the canister filter hoses and attachments did not do, which lead to a film on the top of the water. Replacement filters are reasonably priced and easy to find.The con is that I find this unit very loud. My tank is located in a mostly-unused room. If I watched TV in this room, it would have returned the filter. The sound of the water falling into the tank is nice. It is the motor that is loud to me. I'm not sure if this is normal, or if I just got a bad unit. Also, the flow of the water cannot be adjusted. Some days you need more circulation and others you do not. This filter has one level only.Overall I like it and my turtle is happy.

This filter is amazing in my 25 gal fish tank. I have little ones that are constantly trying to mess with the fish tank, and I had to replace my last filter, due to said little one getting to the old filter which sat on the outside of the fish tank. Once I got this filter in the tank, we no longer had issues with them trying to get at the filter! The setup was super easy. The suction cups work well and keep the filter at whatever position you place it, and there's also an option to hang it with hooks on the inside. Once its up and running it performs wonderfully. I haven't had any issues with it since purchasing around 2 months ago. It is super quiet, only making light noises here and there as the water moves around. It has done an amazing job at keeping my fish living in a clean and healthy tank.

By far my favorite brand of filters and they last so long. ( I have a 20gal that’s been going for 5 yrs.) All filters are usually loud but this one isn’t as long as you keep the water level high enough. I was expecting it to be big but this one really came in big.

Just got it and I wish it was both less noisy and a bit more powerful for the price. I think however if my aquarium wasn't in my bedroom the noise level would be acceptable. It has decent suction but I feel like it could be stronger considering the size of it

Bought this for my sons aquarium. Turned it on and knew instantly that it was going back...between the vibrations and the filter noise...it would keep my son up all night. For someone who doesnt mind the noise, great filter.

does a good job filtering water. Suction cups don’t always grip easily.

Great filter ! Absolutely silent, arrived 1 week earlier than expected and easy to assemble and to place ! My fish were getting sick because the old one stoped working but now they are fine !

The media could not be loaded. Ordered Sunday. And in today just started using it I will update after a couple of days
