hygger Hang On Aquarium Filter, 127GPH Rotatable Surface Oil Skimmer, Quiet Power Fish Tank Filter with Adjustable Water Flow Retractable Water Inlet Tube for Freshwater Saltwater Tank Filter (S/M)

Fantastic little filter. It may be affordable, but this is probably over-designed for the price point which is certainly a benefit to the end-user. Most hang-on-back filters like this do not have a surface skimmer. I've had several canister style filters with built-in surface skimmers, but those almost either never spin or spin for a bit and eventually just stop (and need constant cleaning). Immediately I noticed the intake tube for the surface skimmer is a smaller diameter than the main intake tube. There may be a few positions depending on your tank layout and where the filter is placed where the skimmer won't spin, but I've got it in a sweet spot where it spins constantly. It can spin quite fast too depending on the rate of flow which is adjustable.Once you open the filter, you'll find that the water intake tube then leads to a separate tube that feeds directly into the filter boxes, meaning the water goes straight into the filter box, runs through the media then comes back out into a gentle waterfall. There are two separate filter boxes which open into a small chamber which comes with some coarse foam sandwiched by fine filter pads.If you're looking for a filter that provides high flow throughout a nano tank, you might want to get a more powerful filter, but for everyone else this should be more than sufficient. When the filter is running it is nearly completely silent. There is a slight hum from the motor and at half-speed in my tank, the water falling into the tank makes zero noise.Really impressed by this filter. It is now going to be my primary choice for filtering nano tanks.

I had to replace my previous Aqueon filter when it stopped working a few days after the warranty ran out. It was noisy at the beginning, but then just got more and more so until the motor burned out. I tried everything - cleaning it, replacing the pads, etc. Died anyway.So, I moved away from Aqueon and bought this one by Hygger. I had already bought their mini air pump with hose and small air stone for my tank and absolutely love how quiet it is. So, time to give their filter a chance. Holy cow is this thing quiet! I hardly know it's there. And I love how I can adjust the water flow, how it forces all of the water through the filter pad, and the surface skimmer is spinning right along. What a neat concept there! Now, as long as it doesn't fry up I'm golden!

This is a low range waterfall filter, and you should not buy it because it is a tremendous waste of space for what it does.I am an experienced fish keeper and run a fish shop attached to a garden center. Each year, I'll buy 10-20 affordable pieces of fish equipment (filters and heaters etc) from different suppliers, so I can recommend affordable options to customers. It's also great to have a store of 'backup' equipment ready to go in case some catastrophe strikes in the shop...Which leads me to my honest review: there is simply no reason to buy this filter. Its not good at anything it should be good at. The 'filter' itself is quite large... but the volume of it inside that is actually doing anything is tiny. Inside is a tiny filter box that is the size of any micro filter you may have owned previously. Yes, you read that right- most of the volume of the plastic case is just empty, mainly to achieve the spillover waterfall effect. One filter sponge (smaller than the size of a dollar bill) is all the filter can actually house. Some filters have capacity to add extra sponges / stones / carbon, but this filter deals very badly with any extra 'add ons' as the filter itself and the suction it provides is so weak already.Having a tiny filter box isn't criminal, but the issue is SO MANY OTHER waterfall filters for a similar price point do the job 1000 times better.The filter offers a small cog you can use to go from low flow to hi flow. I don't know if my model was broken, but I really didn't notice much of a difference on either setting. Even more irksome was the motor inside the filter is tiny and can get blocked by grains of sand etc. It honestly felt like my filter was missing a key part or something.DO NOT BUY - OTHER WATERFALL FILTERS ARE AVAILABLE FOR THE SAME PRICE POINT.

I got this because I really needed a surface skimmer for my nano tank. I really didn't want to replace the filter I had because it was super quiet and effecent plus small. This one works really well I'm happy with it so far. The reason why I didn't give it 5 stars is because the intake tube is way too long and I think it's causing issues with keeping the skimmer spinning as the instructions say "they can't overlap". I currently have the tube pretty much as far in as it will go and it still touches the bottom of my tank. I have to keep the water level higher than I usually do so that the skimmer will spin. My filter is also a bit noisy. I believe this is being caused by the skimmer as well as its quiet when the skimmer isn't moving. Overall I'm pretty satisfied as I no longer have to deal with all the surface scum and whatnot that used to be at the top of my tank. The water in my tank is crystal clear.

The filter lasted only two months before failing, but the company's outstanding customer service quickly replaced it, turning a potentially frustrating situation into a positive experience!

Overall seems rather good quality. Comes with a low density foam cover for the intake to protect shrimp and fry. The removable filter is an awesome touch, and cleanable to boot. My only complaint is the ' protein skimmer ' doesn't really work (on high and balanced it barely spins) and if you have snails, it will suck them into it and keep them there (one of my mystery snails got stuck and died in it). I wish there was a cap to block it off easily if you didn't want the skimmer.Overall, I'd give this 4/5 stars.

Bought this for my 10-gallon aquarium. Works great. Love the skimmer that circulates the top of the water.
