Bio Fish Aquarium Mini Cylinder Soft Sponge Water Filter, Black

Fast shipping and much bigger then I thought it was. Although I assumed it came with the air tubing that connects to the air pump which it didn't but that's ok. Looks like it would easily do what it's supposed to but I ended up not using it. It turned out to be a bit too strong for my low tech 6 gallon ranch as I wanted just minimum service distruption. Oh well I will save it for a bigger tank I plan on upgrading in the feature :)

It's a sponge filter, cant really go wrong there. The weight at the bottom isn't heavy enough though, I'll stick with suction cup mount style.

i thought this was a filter, but only a replacement part for a filter.

Smaller than expected but I like it and it seems to work well.

I have 7 tanks, and now have 7 of these filters. One in each. Keeps the water nice and clean and the fish are much happier with the oxygen in the water

first sponge filter I've ever used and I'm loving it so far water a lot cleaner and it's picking of the waste in my snail tank

Satisfied with purchase it got here way sooner than it was suppose to arrive. Hooked it up and everything worked fine and perfect size.
