uxcell XINYOU XY-380 Aquarium Fish Tank Biochemical Sponge Filter, 4-1/2-Inch (1-Pack)

A set of three I put two in a 80 gallon tank and one in a breeder tank

I use this filter sponge on a 55 gallon tank with fish in it. It works great for added oxygen to the tank at the same time helping to filter the tank. I have it in the corner of the tank and its perfect. It has a weighted bottom to keep it from floating. I pull it off every month and rinse off the sponge and put it back in the tank. I would highly recommend this to anyone with multiple fish tanks.

Great for the tank and easy to clean.

You will not be disappointed with these sponge filters they are large providing a lot of surface area for bacterial growth needed for bio-filtration. Priced right!!!

What could I say they work great cheap best price online I run about 40 of them

Bigger than expected and really good

Filters for aquarium and power head. These is a good product if you need of feel that you need some extra filtration. I assembled them with little effort and they work great to get the little debris in you tank.

Couldn’t read directions. In another language.

Awesome! I have two in my goldfish tank and it’s doing amazing at keeping the tank clean and healthy and cycled!

Good for money worked for as long as I needed it
