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

These filters are wonderful for raising fry. I raise tilapia and they filter the water without killing the fry

Perfect for raising fish fry

Works great

Great sponge filters for the price, a bit large but do work well.

So far no issues

Works great as a supplemental filter, mechanical and biological, for my 40 gallon tank with about 20 to 25 fish in it.

Does exactly what it needs to do. I have no complaints at all. I modified it to fit an air stone and BOOM, new kind of filter.. Ordering more as needed.

This is like my 13 sponge filter. Works great

5/5

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