hygger USB Single Sponge Filter, Small Aquarium Filter with Adjustable Hanging Clip and Suction Cup, Duckbill Outlet, Rain Pipe Outlet, Extra Spare Sponge

This filter work very well. The pump makes almost no noise, all you hear is the water flow. It's definitely worth the money. It's easy to setup and clean. My fish love it and so do I

Make sure and check the measurements. I was trying to upgrade a small pump and thought this would fit in my small tank but it didn’t. Good reason to upgrade to a bigger tank.

Update: it was user error. I realized after re-reading everything several times that I needed to squish the living daylights out of the sponge when I cleaned it. It's a beginner's error, as I thought I needed to be gentle with it. Once everything was clean, everything started flowing so nicely! However, still not full stars because the sponge does seem to be getting clogged/full rather quickly, after 2-3 days the water flow is starting to diminish already. Otherwise, it's great price point for a sponge that has its own pump included, plus the biomedia and flexibility to add to the container (I added a small amount of charcoal, for example, and previously seeded with old media). The flexibility and price point is really great for someone beginning the hobby!I'm so sad and frustrated. At just 4 days past the return period, I cannot get this filter to flow normally again. I cleaned the sponge at least 1x a week inside and outside, and scrubbed the intake. 2x within this month, I disassembled the pipes and scrubbed with a toothbrush and straw cleaning brush, and made sure to clean the little individual outlet holes of the "rain" attachment. Last night was the 2nd time I cleaned it this way, and for good measure I also opened the media recepticle and made sure it wasn't clogged with anything, plus scrubbed the intake from within that area. This filter has been steadily declining to now only outputting a dribble of water, and now I'm afraid my nitrogen cycle is crashing and my fish look stressed. There is no way to contact the seller after the 30 day period to try to troubleshoot, I cannot take the filter apart any further or I would void the warranty, so now I'm left to writing this review.

Still working, gentle enough for beta and shrimps. The tube is directly under the cover lights and had turned green, but water quality is still good.

Exactly what I was looking for. Waterfall wand still going strong after a month! Will buy again.

Great !! Perfect for my nanotank - low maintenance. Great affordable all in one device.

It’s really quiet, but very large. Barely fit in my 5.5 gallon tank, but I wanted to make it work. Before inserting the new pump and filter, I did a 50% water change and cleaned the gravel. Parameters were good. After 5 days of use, I noticed the water looking a bit off, so I tested the water and the ammonia and nitrites were elevated. The only thing different, was the new pump/filter. So I agitated the gravel a bit, finding more than usual bits floating around. After, I watched near the filter, 90% of debris floated right by, not being sucked in at all. The water flow seemed fine, pretty slow but that’s what my betta needs. I guess it’s too slow. I took it apart, cleaned it and put it back in, hoping it would be better. But still, most particles still just floated right by. My betta looks rough, I’m really hoping he’ll make it through this.

Not so eficient to clean water, but it helps to maintain small acquarium. Good for fish nursery.
