    We recently acauired an unplanned fish so I needed a cheap filter for a 10 gallon fish tank quick. I also wanted one that was relatively quiet. This one was the cheapest and it had relatively good reviews, so I decided to try it, and I’m glad I did!After plugging it in, it made noise for a few seconds, but then went completely silent. It took only a few minutes more to clear up the water.Finally, the water flow was strong enough to circulate the whole tank without being so strong it pushed the fish around.I would recommend.Standard pen shown for size

    I was well past time to get a new filter, but I didn’t want to get another “bubble” filter that ran off the air pump and used weak suction cups to hold it to the side of the tank. It never worked very well, and at least twice a week I had to reattach the suction cups to the side of the tank because the filter was just floating around.This filter is perfect. I wish I hadn’t waited so long to get it. Within a couple hours all the stuff I stirred up rearranging the decorations in the tank was gone. The water is crystal clear now and I can really see the water circulating all around the tank (fish food follows currents all over the tank instead of just sitting on top like it did with the bubble filter).In regards to some of the bad reviews…I don’t know if perhaps you got a dud or something is out of alignment or adjustment…but I can turn off everything and stand right next to the tank and I don’t hear a thing. It is completely silent. After reading some of the reviews, I was worried that the impeller might make too much noise and upset the fish, but it doesn’t…it doesn’t make any sound at all.And for those who are worried about the little holes at the bottom where the impeller is…you can always take a bit of screen or loose sponge (like a tank brush) and put over it. My cardinal tetras don’t seem to have a problem with it at all. I’ve seen them swim right past the bottom of the filter and nobody has gotten sucked up into it or a fin caught or anything so far.I’ve only had this about a week now, but I can’t think of a single reason not to buy one if you have a 10 gallon or smaller tank.

    I have had this for 3 months so far. It’s nice to not have to worry about water spilling out of the tank as with the “hang on back” filters. This filter has same power and ability as my previous hang on back. Others here have stated an issue with their fish getting sucked into the intake. I find my zebra danios have zero issue. As others have stated here, maybe if you have weak swimmers then the solution is to put some mesh over the intake. This filter is much quieter than my HOB filter. Changing the filter is super easy and inexpensive.

    Its good for my bettas in their 5 gals. However the impeller blades at the bottom can easily suck in and damage fins (as it did to mine). But u can fix this if u keep reading… I had to put some filter media bags over the bottom of the filter to make sure no more fin sucking could happen. The media bags blocked the intake a little bit (which you really dont want) so I cut some tiny slits in the bottom of the bag and now the intake flow is just fine.Its honestly hilarious to me that there still isnt a perfect betta filter on the market. With virtually every filter you buy you have to DIY at least one thing about them. Did the creators of this filter really try it out in their own betta tanks? The intake is small and weak, yes. But betta fins are extremely fragile and will be shredded to pieces if it gets sucked into anything. The out flow is perfect for a betta though. Especially if you have lots of plants in there! The plants will block the flow even more.Some other things: There is plenty of room for a filter media bag of peat moss or whatever. Its a little noisy at times but it never bothers me and I have 2 of them in close proximity to my office desk. Also you can fix the noise sometimes by just nudging it around a little bit. I also like how the intake is on the bottom and not the back. Because the betta sometimes swims behind the filter and I wouldnt want him getting suck in thru the back. Pretty easy to clean. Pretty much perfect suction power and flow rate even with the media bag blocking it.

    I’ve used many filers over the years, of various brands and styles. This is my absolute favorite. I have purchased several from Amazon in various sizes for different tanks. They are more powerful than standard back-of-the-tank filters, are much less likely to become clogged, and since it is a single piece, much easier to clean. It can hang at an adjustable level, making it ideal for both aquariums and turtle/newt setups. I have them in use for turtles as well as standard aquariums, and am thrilled. Obviously, in the turtle tanks there is more of a trickling, waterfall effect, so it is louder but not unpleasant.Definitely worth purchasing!

    Their are two astonishing things about this filter – the low price and the quietness of its motor. I’d bought it to replace an undergravel filter which stopped function because a nozzle piece broke off as well as the air pump which sounded like a DC-10 taking off. Installation was easy peasy; I didn’t need the included suction tabs. The silence of the filter was really necessary because my 10 gallon aquarium sits on the same table as my computer recording setup. I waited all day to write this review because I wanted to make sure the three fishes (Winken, Blinken & Nod) were okay with it and weren’t starving for air since the pump was removed. I read on several websites that an air pump wasn’t needed because my setup didn’t have live plants, only had three fishes, and was just a 10 gallon unit. The little waterfall created by by the filter agitates the water enough to forced oxygen to circulate through the water. I’d say this was a good bye.

    I got this filter because I have gotten other tetra wispers before and had great results. I was a little worried because some review said it was bad for betta fish but decided to give it a try. I have two very young female baby bettas in a ten gallon as well as 2 baby african dwarf frogs and they love it! The flow is soft and very gentle so it was perfect for my baby’s. I’ve had it in my tank for a couple months now the filter is still running great and my fish have never had any issues.I keep it in my room and you can hardly hear it just a soft white nose sound. Keeps my water crystal clear . Great filter definitely recommend.

    Originally I bought a smaller size one from PetCo which was obnoxiously loud so I end up buying this one and let me tell you! It works amazing. It’s very quiet as long as your tank have water high up till where it’s suppose to be. If the water is low for your tank perhaps for like hermit crab or turtle set up tank than it’ll definitely give nice water fall but it’ll be noisy but it still isn’t a bad product. Keeps my tank very clean and my fish happy. I did rinse the filter before using it. I added a picture of before cleaning the tank so you can see that at the bottom of the filter where it sucks up the leaves are there and it works.UPDATE: My previous ordered filter stopped working so they sent me a new one and works great as I written.

    Great filter and I bought two, one for a 5 gal and the other for 10 gal. Yes the flow is a bit harsh for Betta, but I managed to attach sponge bio filter at the whisper’s outflow lip, please see pic. I drilled one hole at each corner of the lip and attached the bio filter using thin zip ties. I also managed to get the suction cups onto the back of the whisper. Getting the suction cups was difficult, but using a precision flat head screwdriver and patience, it was easier. With the suction cups I can close the lid flush to the tank. I had the topfin silentpower filter 10 before this whisper, and the whisper cleans it better and the filter cartridges are cheaper. The whisper is not too loud, but louder than other filter I have, the marina slim 10. The marina slim 10 cleans pretty good, but it’s a power filter with the reservoir overhang on the back. I like the whisper internal filter more because I can lower the water level in the tank but lowering the filter itself. With the marina hanging over the top edge prevents you from lowering the filter, therefore when the water level gets low, you get more splash which my Betta didn’t like. I also used the bio filter sponge on the marina to slow it’s output flow with Max inflow setting. Also used a zip tie to attach the sponge on top of the lip instead of below it’s lip. Well i just wanted to share how I modded this whisper and other filters. Which one is best depends on the fish? For my Bettas, the modded whisper and modded marina are good with slow flow rate, good clean output, and reasonably priced filter cartridges, the marina doesn’t filter as well as the whisper IMO. So I use the marina for 3 gal tanks for my bettas.

    The filter works just fine, it is slightly noisy but nothing extreme. I use it in my 10 gallon betta tank and the current isn’t too strong, my betta will occasionally swim in front of the current and play and it never causes harm or tears his fins. It’s also calm enough that he isn’t having to fight swimming in the current or being pulled around the tank; however I don’t see this as being a filter for under 5 gallons. The slats on the bottom were a bit wide so I did have to add a protective netting so if my betta swam too close his fins wouldn’t get sucked in or damaged. I haven’t had any issues with this filter. The drop in option where the filter hangs off the edge is nice as well because I didn’t have to worry if it would fit my tank’s hood, the slim bar easily fits even the smallest filter openings. Trying to fit the suction cups was a bit awkward as the slightest bobble would pop the hook off the cup but we got it sorted out. Overall pleased with this buy and pleased with the water quality
