hygger Small Aquarium Bio Sponge Filter Mini Fish Tank Filter for Breeding Fry Betta Shrimp Tank 2-5 Gallon (Small)

I'm not one to leave reviews, unless absolutely necessary. This is my second review in maybe ten years, and this product deserves a review! I'm not a professional, but I have a decent amount of experience with fish/plant aquariums. As of now, I only have a small tank setup and have been experimenting with self sustaining ecosystems, which I have accomplished. I went back to using a filter to enjoy more creatures in my tank and handle the heavier bioload. I've been experimenting with hang on back filters, internal power filters and different sponge filters. I decided to try this filter also on and off for about a year, because of its unique appearance. Here is my experience.. I keep going back to this filter! It pulls, but very gently. The build quality is nice. It's suspended off the substrate, which frees up a lot of space. It keeps my water stable and clear. The fish behave more naturally with this filter also, which I get mixed results with other types of filters. I don't know if it's the setup and combination of the sponge and media, but something about this filter keeps a healthy tank. Cleaning this filter is very easy. Just pour out the media and separator into a container with water from the tank, give the top a firm tap like a ketchup bottle, and the sponge comes out. Squeeze the sponge in the cycled water a couple times then reassemble. There's really no need to share pictures of this product, there's enough of those in the reviews. My only complaint is the suction cups do slowly release from the glass in a couple weeks. I don't know why some companies still have a difficult time supplying reliable suction cups for their equipment.. I'm probably going to make a hanger for this filter in time to replace the suction cups. Suction cups aside, this filter deserves a five star review for its effectiveness, ease of use and appearance!

My friend has this same filter and it works great. I ordered it and it didn’t work at all. I hooked it up to my pump and nothing happened. I then tried to blow through the tubing myself and no air was passing through no matter how hard I tried. Upon disassembling and checking it, there is nowhere for the air to go. The inlet is a sealed up piece of plastic… as if they failed to drill it all the way through. This is a pretty serious manufacturing defect. I’m quite disappointed, as I own other Hygger products and have always been happy with them. This one is certainly a miss.

This 3-in-1 filtration system is definitely worth the hype. It’s been going viral on TikTok lately, but I actually discovered it through Amazon. After using it, I can confidently say—it lives up to the praise. The filter does an excellent job of clearing up the water fast. Honestly, it started working within 10 minutes of setup. My tank looked noticeably clearer almost immediately. It also adds oxygen and uses biological filtration balls, which help keep the water clean and healthy for my fish. I’ve tried a few cheap filters before, and the difference is night and day. This one had a ton of reviews, and now I understand why. It’s powerful, but gentle—the water flow doesn’t stress out my fish or force them to swim harder, which I really appreciate. One small tweak I made: I replaced the black sponge that came with it. It felt a bit too flimsy and wasn’t catching much debris. I swapped it out for an AquaClear sponge, trimmed to fit the original size, and the difference was huge. Better filtration all around. If you’re starting an aquarium or just looking for an affordable, reliable in-tank filter, this is the one. Sure, there are TikTok deals, but I stick with Amazon and I’m glad I did. Five stars from me.

The first one i got was already like put together which i found strange and then it didn’t work. So i got a replacement, which was super easy and fast, and this one actually came packaged separately and seemed untouched and it works beautifully. I have it in a 2.5 gal and its perfect. Hand for size reference. Its only been plugged in today so i cant vouch for longevity.

This is the perfect filter for my small tank. I have tried several others and my betta either gets pulled into it so he hides from it, refusing to eat or it has so much noise and water movement that he refuses to move. This one is PERFECT. Elvis swims near it, and actually seems to like it. The water is clear and is getting good aeration. In100% recommend this filter.

I have 2 of these. 1 is in a planted 10G tank with a small bioload and some cory catfish to keep it clean. It works very well. 2 is in a 20G long tank and it works, but needed some assistance. It's a good value for money, in that the machine itself works well. We replaced the sponge with a better triple layer and the biomedia is split between whT they provided and purigen. It sucks to clean, tbh. A full clean isn't necessary except for every 6 months (don't ruin your bio), but you still have to pour out the media to rinse the sponge in the tank water though. I wish it had a little pull out drawrr or something where I could access it separately from the central media. Otherwise, it's quiet, bigger than expected, and easy to use for sure.

The air from the the inlet tube leaves the exit spout with less than an inch of bubble travel. Where is the lift to draw the water from the bottom through the tiny sponge ,through the ceramic balls and finally out the spout? Literally none. nada,nope. The diagram illustrating the intended waterflow looks pretty but that’s it. I took it apart after 4 months and the sponge was clean almost like new? whereby I had cleaned my sponge filter 4 times each time colouring my bucket water like chocolate milk. Your not going to tell me my sponge filter is so powerful that it didn’t leave anything for the Hygger? What it tells me is I paid over 25 dollars CDN for an airstone. The reviews stating they would not recommend it as the primary or sole filter are being too polite. How Hygger techs could release this design is beyond belief. How not one person stood up and said” Hey this design doesn’t look like it will work. Don’t forget. Hygger makes sponge filters….all kinds,power sponge filters…all kinds. The reviewers saying that it’s hard to remove the cartridge because it snaps together so tight are 100% correct. In retrospect. if the filter doesn’t get dirty,then we don’t need to take it apart, right? To add insult to injury, you have to dump out the bio balls to get at the sponge. I do not understand the amount of positive reviews.

Funciona perfecto para peceras de 10 litros

I wouldn't use this as a primary filter but it's good for airflow and a little extra filtration doesn't hurt.

Working great love it

Malísimo, primero no explica que debes comprar adicional una bomba de aire y aún cuando la compras el conector de la manguera está tapado por lo que no permite el paso de aire por ningún espacio. Tiene error de diseño o algo similar dado que es imposible qué funcione
