hygger Submersible Aquarium Power Filter for 3-30 Gallon Fish Tank Corner Internal Filter with Bio Ball Sponge 3-Stage Filtration System (120GPH)

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!

Installled this in a 20 gallon planted tank and added an air pump since it had the inlet feature which is nice. It moves the water well and filters really good.Only gripe is cleaning the filter media. Removing it and cleaning everything out and putting it back is a task and disturbs the tank more than I like. May have to modify my lid so that I can put an over the back filter which is more convenient and less bothersome to the tank.

Great filter with a few aeration options.

The media could not be loaded. 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.

The media could not be loaded. I use this filter in both 6 gal and a 3 gal aquariums. They are powerful and quiet. The best filters I've had. I like that it has the option for 3-tiered filtration but it works so well that I may forgo carbon altogether to reduce using pre-filled cartridges. I use Seachem products and my water is pristine and healthy. As you can see in the video, I use the waterfall feature. I put in the lowest flow setting. The current doesn't sink food or disturb the fish. I have a Betta and 3 Tetras in my second aquarium and the current doesn't bother the Betta either.I tested three filters before deciding on the Hygger filters. The other two were ZooMed Betta Clean and Penn-Plax Cascade 300. I wanted internal filters. Unfortunately , the noise and water flow of these two models weren't to my liking. I was concerned that the Hygger filter is listed as a frequently returned item but I'm glad I decided to try it out. It's definitely an option worth exploring.

This filter is probably best for aquariums that do not have live plants because it clogs very quickly due to the small intake space.The air intake tube has never functioned.The spray bar also grows algae quickly which is annoying. Hygger usually makes great equipment but this one fell short of my high expectations.

I quite like this filter for my 10 gallon tank. It's easy to maintenance, works well and isn't that loud. Definitely keep smy water clean but I do have to clean the filter media out each week to ensure goo flow.

Pump output already decreased significantly after just one month. I kept the media clean and the tank only has seven small fish (grow out tank). Maybe I got unlucky, but I'm going to go with another filter that I've used before and know is reliable.I really like the concept and aesthetic, maybe a stronger/more well built pump would be better. Giving it a star due to the concept and variation in filter media in compact form.Also due to the pump being quite close to the surface, if you are away and the water level decreases due to evaporation, it could begin pulling in air and damage the pump. Something to keep in mind!
