5 Gallon Aquarium Filter with Surface Skimmer, Small Quiet Fish Tank Filter, Biochemical Cotton Filtration & Adjustable Water Flow, Waterfall Design for Increasing Oxygen, Hang on Back Filter

The media could not be loaded. I’m using this for my small 20 cube tank. In the tank, I have live plants, soil, and dragon rocks. Planning to get a betta fish soon. It’s made of plastic. I used my own filter media and cut the sponge to fit in (3rd picture). When I saw many negative reviews, I noticed they didn’t follow the directions such as minimum water level, etc. You also need to fill the filter with water before plugging in. It’s working perfectly as expected. The filter doesn’t make a sound after properly starting. It’s cheap too! If it’s broken, I will buy the same product. In the picture, I intensionally blocked the outlet with my plant hanger to slow down the water flow, but you can also adjust it without doing so.I didn’t use the skimmer because my new betta doesn’t seem like it. Without the skimmer and blocked water flow, he swims peacefully and doesn’t swish due to water flowUpdate after 1 week of use:Still five stars. I didn’t use the skimmer at the first time, but noticed there is some oily surface. Added skimmer, and it works fine. Attached the video for sucking up the floating plants. It removed the oils on the surface and my betta swims ok.

Exactly what I needed and great price! My nano tank was getting a bio film that was out of control- this cleared it right up without disturbing my betta.

The media could not be loaded. Can’t even use it bc it’s so loud I fear it will kill my fish purely bc of the stress

Awesome filter for a betta tank! Love the skimmer as well , only reason i didnt give a 5 star was bc its a little loud. But other than that it works great its flow is adjustable which is great ! Skimmer catches a lot !

I’ve had this for some time now and it’s been very functional. I recommend removing the sponge at the bottom in order to pick up bigger bits of debris. It’s amazingly silent, and the length is very customizable. Very nice value.

I bought this for a 3 gallon tank with a single betta fish. It hadn't even occurred to me that the opening around the surface skimmer attachment (piece shown in the photo) was just big enough to suck down my little fish friend where he got stuck in the plastic pipe and died :-(It's a really great, quiet, and efficient filter and you can use it without the surface skimmer. I blame myself for "user error" but am obviously sad about having purchased this.

I ordered this as a replacement for the pump that came with the aquarium. This pump is slightly different. The tube is not as long (missing the small extender section) and it didn't come with the sponge screen filter for the end of the tube. The biggest disappointment is that it isn't as quiet as my old pump was. That one was practically silent. This one is quiet, but definitely has a low hum vibration, similar to what started happening with my old pump at the start of its downfall. The old pump did great for 10 months, then started getting noisy. We'll see how long this one lasts. Quality is questionable.

I find this filter a great option for my 5 and ten gallon tanks. It's simple to set up and easy to maintain. Others have complained that it is noisy which I believe is from not using the little round disk on the outside of the tank to make the filter level if not actually tilting forward just a bit. We have these on four tanks and it's a great option for an inexpensive filter that works as well as the more popular expensive name brands. It's made of clear plastic which makes it so easy to see the condition of the filter medium. I usually have to prime them upon start up and after cleaning but that's easy enough to do. My betta tanks are perfect for these filters because I can slow the water down enough for the fishes not to be bothered by the flow, All in all I have to say that this is probably the best think I have ever bought on amazon over the last 25 years!
