Whisper 200 GPH Internal Power Aquarium Filter

Okay so... I have a 20 gallon temporarily for my 4 inch turtle. I accidentally bought the smallest of this tetra filter, so I bought the medium sized one in it's place. I had only had the tank filled halfway anyway since my turtle was only 1.5 inches at this point. Mind you I didn't realize how fast they grow, and had no idea that Its recommended to have a filter that can filter 2 to 3x the tank size. So I decided to keep both filters in my tank. One on each side. Even though I still don't reach the recommended filter size, my water now almost filled to the top, stays absolutely clean. Turtles are pretty messy so I still have to do the weekly cleanings and all that extra stuff that apparently those who spend hundreds of dollars on filters still have to do as well. I don't know if this is some kind of luck thing, I don't know if maybe my turtle just isn't that dirty (yea right, I see him)... but I'm actually not looking forward to switching out my filter for the 'recommended' filter size, as these filters work so good. I love them. They are both very quiet. Aside from the sound of the water falling back in.. I mean it sounds like a waterfall. Who doesn't want to hear a waterfall? I love it. This can also be prevented by raising the water level or lowering the filter itself. Basically the closer it is to the water, the quieter it is. Such a simple device, yet so beautifully sufficient. The little one stopped working at one point and I thought... welp there you go! Get what you pay for. But nope! Removed the base, pulled out the magnetic spring propeller and tube, cleaned it out and like magic it started right up as soon as I plugged it back in. Love how easy it is to replace the filters. The filters themselves are great and definitely hold on to some dirtiness. One thing I'll say is there is quite a bit of unused empty space. I now take advantage by adding some extra media, but I must say that these filters work great even without the extra. Love this filter and would recommend above any other filter.

This filter is keeping my 2.5 gallon betta tank very clean. It super quiet. I would recommend this product!

This is my 3rd filter and finally found one I love. This is quiet and so easy to change out. The only thing I dont like is how low it sits in the tank. Wish the design allowed it to go higher up.

I've only been running this item for a week, but the results have been very, very good. Please see pictures. My daughter has a 40 gallon tank and this moves more than enough water to keep it sparkling clean, even with live plants! The only thing we do not like about the unit is the mounting. You insert a bracket in the back and it leaks if not using the suction cups. If you use the bracket, it is difficult to move up and down and the mount into the actual filter can break off easily because it is simply put on by 2 very small plastic "rivets" and one already broke. Notes: She also runs a sponge air driven filter (slow moving, bio) Likes: Extremely quiet, do not hear it over the air pump. and it's a quiet pump Moves a LOT of water, more than I thought after reading reviews Easy access to filter Big mesh filter, should last a month no problem. A lot of surface area Seems to do a good job circulating the water, and keeping it clean. BUT, not as good as having a tube going down to the bottom like the traditional style Very inexpensive Dislikes Mounting system. It's cheap and wobbly Questionable micro filtering, because the water moves so freely through the filter, thus get a sponge filter to compliment it and put it on the other side of the tank like we did. (see picture). For a smaller tank it won't matter Summary: We don't care for Tetra brand as the quality is usually mid grade, but this one is good, inexpensive and quiet. We only wish the instructions were more clear and allowed for variable flow rates. We would actually slow it down a "tad". This is a great buy for what it does.

The main factor is that it arrived the same day I ordered it. That action is greatly appreciated, not only by this customer but by Moco, my Red-Eared Slider. He has been with me for many years, and he deserves the best care.

I recently set my smaller fish tank back up to put some fish out of my main tank into (tank full of guppies and a couple algae eaters) as one of the “algae eaters” has begun to jump through the water and swallow my guppies whole. I had the filter left over from a goldfish I had for a few years in there and figured it would be fine. When i moved the fish into said smaller tank i moved six over and then a smaller one ended up popping up (making it seven fish) i went to sleep and all were fine. When i woke up i noticed one of the fish i had put in there had died, the next day (today) FOUR MORE were missing when i woke up. Two had gotten tangled in a fake plant and died (i figured it was fault for putting it in with the guppies) i then watched one of two remaining fish be blown into said plant by this filter as i was investigating. I saved that fish but it was somewhat weak (i was actively treating the tank for ick) so i let it be. i CAME BACK ABOUT FIFTEEN MINUTES LATER TO ONE FISH. i figured it had went into the little structure i have in my tank, it had in-fact not. Instead i found it another fifteen minutes later when i saw something peeking out of the bottom of my filtration system. It was the tail of A DIFFERENT FISH that i figured had passed in the fake weeds. Upon seeing this i pulled the filter and was appalled to see MY LAST FEW FISH I COULDNT FIND HAD BEEN EATEN BY THE FILTER. Two of them were dead- i then had a half paralyzed fish that died about 30 mins later. Ive now unplugged the filter with ONE OF SEVEN FISH LEFT AFTER A DAY AND A HALF OF USE. I Strongly advise against getting this filter if you have guppies as it may cause a quite disturbing scene. ALTHOUGH this filter killed a bunch of my guppies (literally sucks so hard it ate them) it WORKED GREAT FOR MY FULLY GROWN GOLDFISH for about a year before he passed so that is something to take into account. Personally i think it should be advertised that this filter CANNOT HANDLE SMALL FISH NO MATTER THE TANK SIZE.

Broke already- purchased like four or five months ago. I only have goldfish and I don’t have plants. I use gravel, not sand. Regular water tanks never let it get low. Disappointed.

When you open the box, the Whisper 40i (or it's smaller siblings) don't seem very impressive. It's not much more than a oval plastic bucket, with another bucket (containing a motor and pump) snapped onto the bottom. If you looked at one and thought "this can't possibly work", you would be so wrong. Perhaps they work as well as they do BECAUSE they are so simple, and so have little chance for things to break. The pump sits IN your aquarium water, so it never needs to be primed. You plug it in, and it begins working, filling the upper bucket, where the water flows through the filter pad and spills back into the aquarium. No priming necessary ever, including after a power failure. When the power comes back on, it just starts working again. It's a shame that every hang-on-the back power filter can't make a similar claim, some unfortunately will lose their prime and/or fail to restart, resulting in unhappy fish and sometimes a damaged filter. There are no adjustments for flow, so these only run at one flow rate. Inevitably, some food can get sucked up if you let it run while feeding. I have the filters on a separate power strip, so when I feed my fish, I just use the switch on the power strip to turn the filters off for an hour or so. Easy solution and prevents the filter pads from clogging so quickly. There is no top or lid (unless you buy the model intended for reptiles), so the filter pads just sit there exposed. This means that the water in the filter is fully aerated as it passes through the pads. It also means that no other internal filter is as easy to change pads when they become clogged. The top edge of the pad is above the water line, so you just grab it with two fingers and lift it out. You don't have to disturb the suction cups or hanging bracket at all. You don't have to put your whole arm down into the tank. Maintenance which is easily performed is more likely to be done when needed, so easily changed pads are more likely to be changed when clogged. You have options for how you want to attach the filter. The box includes two suction cups, and a newly designed bracket which hangs over the edge of your tank. I use the bracket, as it's adjustable for height and I don't have to worry about suction cups losing their suction. The filter pads are the Whisper bio-bags, which amount to a thick fluffy poly bag, over a plastic frame, with carbon granules inside. Replacing these is simple, and if purchased in a 12 pack from Amazon, cost about 60 cents per bag. I used Emperor filters for years, and in my experience, these bio-bags work a lot better than the filter cartridges for Marineland products and cost much less to buy. If you rinse them under tap water, which is easily done, the cost is even less. Rinsing the bags doesn't disturb your biological bacteria since they are on a separate part (resembling a hair brush) which remains in the filter when you remove the bags. You do have some flexibility with regard to media options as well. You don't have to use the carbon which is included with the new pads. You can put anything you want inside the bag, and if desired, transfer it to the new bag next time you change them out. You also don't have to use the separate biological "hairbrush", and if you leave it out, you have room to put another media bag in it's place, with ceramic rings, or whatever else you can think of. I have four of these, mounted on two separate tanks, one 55 gallons, the other 75 gallons. All four of them are not quite silent, but very quiet. There is a soft, low hum from the motor windings, a little bit like a transformer humming. At first there was also a faint sound like air trapped somewhere, perhaps cavitation in the pump? But these sounds are hard to hear, and not distracting. And the cavitation sound went away on it's own after a few days. I can hear the soft humming sound if the room is totally quiet and I stand near the tank, but if there is any significant sound from conversation, crunching breakfast cereal, a radio or TV, etc, then they are drowned out. Some of the complaints others have mentioned in their reviews sound a bit like operator error to me. For example, one person said the filter overflowed and sent water over the back of the tank onto the floor. Clearly, the filter was mounted too high....mine are mounted with the top edge 2 inches below the rim of the tank. When the filter pad becomes clogged, it WILL overflow, but into the tank, not out of it. Some describe loud mechanical noises, which sounds to me like a bit of gravel, or perhaps a snail, found it's way into the pump impeller. Yes, this can happen with any filter, regardless of brand, but it's easy to repair. In these filters, the bottom just snaps off, exposing the pump impeller, which is then easily removed for cleaning. And some have complained that the filter "stops working" after some months of service. Again, this is likely due to a need for a cleaning of the impeller and the recess where it sits, where debris or gunk sometimes builds up and prevents it from rotating. On a benefit/cost basis, these filters look really good. They are made of a tough, slightly flexible plastic, so even if you drop one on the floor, it is unlikely to break. Parts for Tetra/Whisper filters are readily available everywhere. And the results are as good as any other filter I've ever used, regardless of cost. The first attached photo shows two mounted in my 75 gallon planted tank, which contains two Nigerian bichers, and two Pictus catfish. The second shows two more in my 55 gallon community tank, with various tetras, cory catfish, and loaches.

filtre tres bien excelent filtre mieux que les filtre beucoup plus cher .je n'est plus de problème avec les parametre d'eau de mon aquarium je l'utilise sur un aquarium de 30 galons . et j'ai complèter la filtration par un filtre auxiliare eponge je recommande vivement ce filtre et la compagnie TETRA mon eau est chrystaline et limpide depuis que j'ai intaler ce filtre et que j'utilise les produit Tetra ce que j'aurais du faire bien avant. et méfier vous pas par son fontionement même si il deborde sont taux de filtration est excelent et tres silentieux il est fais comme ça

Aunque no me encanta que ocupa espacio dentro de la pecera, es un sacrificio que se hace para que sea completamente silencioso. Lo tengo dentro de la pecera de mi cuarto, así que era importante que no hiciera ruido. Le añadí Biomax de Fluval y le corté la pastilla que tiene en medio del paño por que no quiero nada del carbono que le añaden. También le puse una esponja para que no sea tan fuerte la corriente. Creo que es un precio buenísimo considerando el tamaño y poder que tiene. Mi pecera es de 10 G o de 40L así que quedo perfecta. Recomiendo.

The pump stopped working after 6 hours of being plugged in, came with a European plug on it. Brought a new adapter plug thinking it maybe my old one was the problem and still didn't work. £30 wasted, thank goodness my fish survived.

Works great, no noise and tank is cleaner.
