The filter works well in my 10-gallon tank. The black sponge looks sturdy and the water flow is smooth. I noticed a noticeable improvement in water clarity after a week of use. Easy to clean and fits perfectly in the tank setup.

Good filtration performance for a small tank. The sponge holds up well after a few weeks of use. I don’t have to clean it as often as I did with previous filters. Slight improvement in water quality over time.

I’ve used this filter in a community tank with fish and shrimp. It maintains stable water conditions and supports good bacterial growth. The design is compact and fits well without blocking the view.
