I used this filter in my 2-gallon betta tank and noticed a big improvement in water clarity. It’s easy to install and the sponge stays clean without needing frequent changes. My betta seems more active and the water feels fresher.

Works well for a small goldfish bowl. The filter fits perfectly and doesn’t take up much space. I cleaned it once a month and it still performs well after a few weeks.

Great for a shrimp tank. The fine sponge helps keep the water clean without disturbing the shrimp. Simple to set up and maintain. I appreciate that it doesn’t block the view of the tank.

It works as expected for a small setup. The sponge needs to be rinsed regularly, and I found it a bit hard to remove from the side of the bowl at first. But after a few tries, it became easier.
