Small Aquarium Internal Filter

I wanted a filter for my tank that could be put in and removed with a low clearance (we have a shelf almost directly above the tank with an attached light on the bottom of the shelf). This filter did the job. With hangover the side filters, I couldn't get them out to clean easily (it's a 20 gallon tank). This stays to the back corner, out of the way and the noise level is fine - all dependant on your water level as far as the splashing sound. Motor sound we not bad at all. The suction power is definitely not lacking. Many times I had to use a knife just to pry the edge of a suction off the glass wall to get it off. Better to have better suction than not! This was so easy to clean and kept the water clean. I loved the adjustable water flower at the top and the ability to have more bubbles/air go in, or less. The 'rain arm' feature was nice as well. I would definitely recommend this filter for all it brings and all the boxes it checks off. It was a good value (it's still running well over a year later) and is functioning how one would hope and expect!

Excellent. I have a small aquarium less than 5 gallons and this works perfect. Love how you can have spray. Would purchase again. Also quiet.

This worked so well for my 3 gallon tank that I bought another one for a 6 gallon that my husband is setting up. It pretty quiet, sticks on great to the side of the tank and the current is just what I was looking for. I was happy I could find a small submersible filter that had a biomedia compartment. Most small filters only have carbon and mechanical filter options. My only complaints are that it can be a bit difficult to rinse the filter media off because it suctions so well to the glass and the bubbler part of the filter doesn't work. Over all I am very happy with it.

For the price and size, a very good filter. Silent and powerful. Easy to clean. If it makes noise, check the impeller.

I own the model just above this one in another of my tanks and even though, it is not the most silent filter, it does not rattle as loud as this one does. I have no idea why it is so loud, when it starts, right out of the box, it goes with the expected hum and then about 30 seconds in, it rattles so loud that I just want to throw it away, I cannot use this in an aquarium set right next to my working desk. I may keep it as an emergency one or ask for a return, not decided yet. Update 19 June 2024: Hygger reached to me directly after the initial review and sent me a new filter to try and make sure I did not receive a lemon but, this new filter pump is as noisy as the one I received initially. In the attached video taken with an iPhone (which reduces automatically environmental noises), you will have to raise the sound quite a bit to hear it. Once you hear the rattling, it is the actual level of sound it produces in real life. At the end of the video, I switch it off and pane out to the other hygger filter I own which is the model just above and it is mostly silent. When comparing the impeller assembly of both models, the higher model does have a noise cancelling assembly keeping the impeller for moving up and down which this model is not equipped with.

I have a planted nano tank and the internal built-in filtration was comical, so I looked for a submersible filter and found this model. Hygger makes awesome lights. Pass on this. They don’t even make the replacement filter cartridges for this that I could find anywhere. Cartridges usually aren't my thing since better filter floss can be used instead at a savings, but for this model, the filter is kind of sensitive and doesn't seem to want to work without the stock cartridges. That they don't seem to sell at the moment. Today I rinsed off the filter media for re-using and it was nearly black so I cut filter floss I use for larger aquariums and then the filter stopped working. I threw the filter pretty far and now I need a new one. I would pass on this. Frustrating!

At first I really loved this filter. It was strong and did the job admirably. However aft 5 to 6 months it went from having to be cleaned out once a week to twice a week or every 3rd day, which is a pain. I would not buy again.

I put this Hygger filter in a 5-gallon nano tank and wow. I had algae and cloudy water, and within two days the tank was beautifully clear again. I can literally see the back wall of the tank now. The flow is gentle enough for a small tank but still very effective. It doesn’t stress the fish and there’s no strong current, just clean, clear water. It’s also quiet, easy to set up, and fits perfectly in a nano tank. This filter actually does what it’s supposed to do instead of just taking up space. If you’re dealing with algae or cloudy water in a small tank, this one works fast. I’d absolutely buy it again.

The filter seems good but amazon shipped me a 115V product which isn't compatible to the UAE's 220-240V electrical supply, I had to purchase a step down converter on top of this filter which is an additional unit running, which makes it inefficient and costs me more to operate it.

THIS MODEL WAS NEEDED TO PERFORM IN A LARGER TANK AND OUR OTHER UNITS COULD NOT MATCH IT'S FUNCTION.

Quiet. Can’t adjust flow, but can adjust direction of flow. Would purchase for another tank.

Works as advertised and on time.

I did not receive a filter cartridge and filter foam with the filter. Am I expected to buy them separately? If yes, thats very bad. Cartridge and foam should be included as its useless without them. If they are missed out, how do I receive them?
