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

Another great buy on Amazon

These are awesome! We have cichlid babies that were born and we were afraid are normal filter would kill them. The fry xan hang out on this and eat off it. I have a 55 gallon and one does the trick and keeps the tank clean i also have a 105 gallon tank and we put 2 of these in that one and its qorking like a champ. Had them for about 3 months now and still in perfect worling condiiton.

I am just starting a saltwater tank. I cycled it through and bought this. I truly didnt know what or how to use it. I attached it to my power head and now my tank is finally clear. Amazing!

I love it so much

These sponges are great. A little larger than we thought but they really help keep the aquarium water clean and clear. Sponges product an adequate amount of bubbles for surface movement. Recommend customer purchase these as you can also buy replacement sponges when needed. This was important when I was searching for sponge filters Great buy

good

Amazing filters and great price.

Works exactly as advertised/expected! Highly recommended!

i love sponge filter i use in a 40 breeder

UPDATE: its been about half a year since I got the first one for my 40gl. I must say, its doing a much better job than any other filters that Ive used. The water is ALWAYS crystal clear and its so easy to clean the filter. I just bought another one since I will be moving my goldfish over to an 80gl. Also, I must say, they also do a good job doubling as an air stone as they keep the water moving and oxygen flowing through the water. Its cheap, and its totally worth it. I found out about these thing via youtube and wanted to try it out. I love how its cheap, durable, and good for my goldfish tank. Im hoping this will help save money since Ive been spending 100s on just 2 goldfish alone. If anything, its unable to clean up the floating poop, but I can easily scoop that out with a net. Plus, a whole lot of it gets sucked out during water changes. I like the size and cheap pricing. Im definitely getting more of these in the mear future
