Powkoo Aquarium Sponge Filter Foam Filter Little Filter Foam for 1 to 5 Gallon Fish Tank

Not only is it small and cute, but it works. I have it in a 2.5 gallon tank and although it looks a little bulky in my tank, I absolutely love this little filter. If I ever get around to putting my 5 gallon tank together, I would get another (the double one).

Wasnt sure how well this would work but gave it a try. It actually works great for my small tank. Easy to install and gets all those little things floating around. Had to clean the small tank every week, now I dont have to.

It works great. One thing to note: It is not adjustable. You can turn the spout where the bubble come out, but you cannot change the angle of the sponge. I may not have read the description well enough because I was unaware. Regardless, it's a nice quality sponge filter and works great.

Works!

Works great in my five gallon tank. A noticeable difference to the water clarity within 30mins of using it. Ideal for a shrimp or fry tank.

Oddly shaped, takes up more footprint than nessasary, but does the job just fine

It's a good small sponge filter for my 5 gallon tank. Mine did not come with the suction cup which was a bummer but luckily I had some other ones around that would work.

Good product and prices
