Whisper Internal Filter 20 To 40 Gallons, For Aquariums, In-Tank Filtration With Air Pump

I have used these for so many years for little tank setups and my turtle and snails etc. Always work super great and super quiet! Plus they are cheap. No brainer imo. I'm sure theres a faulty one here n there as with anything but keep the propeller clean like any other pump and dont let the filters get too overflowing clogged and you'll be happy I promise. Also with filters of any kind try to get one rated for more than you actually have so the filter doesn't get overwhelmed. Even the filters are cheap for a box of 12 for like $13. Cant go wrong!! 10/10

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 product works perfectly and does exactly what it’s supposed to do. My aquarium looks cleaner and healthier, and everything runs smoothly. Great quality, easy to use, and worth every dollar.

Big Improvement over the previous model. My small tank came with the previous version of this filter and it has a quite significant design flaw that twice caused the unattended tank to lose almost half it's water. Essentially, if the filter was at all clogged with particulate, water pressure would cause the water level in the filter to rise to the point it would flow out of the tank on the clip holding the filter to the edge of the tank. After the second time this happened and a lot of luck that it didn't fry my power strip, I decided it was time to switch filters. While I was prepared to move totally away from Tetra due to my upset over the previous situation, I noticed while researching the change in holding clip. The new design obviously is in reaction to the problem I encountered as it now is architected that even if water were to move back onto the holding clip, it would drain down into the tank as the attackment to the wall is lower on the body. Since I pretty much liked everything else about the design, I decided to give the new version a try. Price-wise it was reasonable and the noise level is very low. Once I received it, it was easy to assemble. My one complaint would be that the box contained two suction cups, but there is no instruction on how they are to be used. That said, I was able to position the filter very easily and the updated design allows it to be placed in such a way that it doesnt interfere with the tank cover. That had been a big complaint I had about the previous design. It was very quick to assemble, get in place, and start using and the speed of the water flow seems appropriate for the smaller tank size. Cleaning is easy since it essentially is just replacing the filter periodically. They do recommend on a yearly basis cleaning the impeller, which should help it last longer.

Silencioso y mantiene la pecera limpia

Its quiet, does the job as an equal bonus my tank is small and it oxygenates the water enough that I don't need a pump

للاسف المنتج 110 فولت ولايوجد في الوصف تحديد للجهاز،وعندنا في السعودية 220 فولت فقط،بالاضافة الى ان غطاء الفلتر غير ثابت،لابد من ارجاع المنتج

Los pocos días que lleva en uso a sido 100% efectivo, limpio el agua de mi pecera a pesar que ya estaba un poco sucia. Súper silencioso y de buen tamaño Hasta ahora todo bien

Plugged it in and it was dead. Waste of time and money, spend it elsewhere. Now I’m left with extra filters that I purchased and a dead pump/filter. Not happy Jan.
