Love, Love This 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.

Easy to use
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.

Great Budget Filter—Super Easy to Use
I love this filter! It is super easy to set up and works great. I literally just clipped it inside my tank, plugged it in, and it was good to go. It keeps the water crystal clear and is surprisingly quiet as long as you keep your water level up. Perfect for small tanks and anyone who wants a no-fuss setup. Definitely recommend!

Super quiet
The first thing I noticed was how quiet it is—you can barely hear it running, which is a big plus if your aquarium is in a living room or bedroom. The filter is designed to sit fairly low in the tank, so keep that in mind when setting it up. As long as the water level is appropriate, it operates smoothly and provides good water circulation. Installation was straightforward, and it has done a good job keeping the water clear. Overall, this is a solid, quiet filter that performs well. If you’re looking for an effective filter that runs almost silently and don’t mind its lower placement in the aquarium, it’s a great option.

Great for price and 2 gallon tank size!
Received this and immediately impressed with how quiet it runs. Nice flow of water and not to strong for my guppies. I do wish it had a second rubber suction cup for on the back if you’re not using the clip!

!!PLEASE READ!! DO NOT BUY FOR SMALL FISH
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.

This broke already. I only have goldfish.
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.

Easy Replacement Filter That Got My Fish Tank Back on Track
The pump on my old filter died, and I could immediately tell my fish were not as happy. My 5-gallon tank was also starting to look dirty, so I knew I needed a replacement quickly. I ordered this Tetra water filter and was able to get it overnight. Installation was very easy—the instructions were clear, and I had it up and running without any trouble. I especially love that the replacement cartridge is a simple, single item. My previous filter had three separate replacement pieces that were difficult to keep track of, hard to find, and easy to forget to reorder. I haven’t had this filter for a long time yet, but so far I’m very happy with how easy it was to set up and how well it keeps the tank looking clean and fresh. It’s a straightforward, convenient solution that makes maintaining a fish tank much easier. I would definitely recommend it to anyone needing a reliable replacement filter.

Súper filtro!
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.

110 V elektriğiniz yoksa almayın
110 V için üretilmiş ürün, 220 V ile sesli çalışıyor ve sonrasında yanarak kullanılmaz hâle geliyor.
