Great for small breeder tanks
Great small filters for my 10 gallon breeder rack. Paired with a 4 outlet air pump makes a great low energy filter solution that won't injure fish fry.

They are not nano
They are big. Should have advertised as small not nano.

Great Nano Sponge Filters!
These are pretty small and one of the 6 I received fit in my 2 Gallon, baby Betta tank without issue. I modded another one with the plastic air valves like in some of the youtube videos. It works better and is quieter than stock. If you are looking for small sponge filters, these might be just what you want.

Easy to install and the Clearest Tank ever!
My three gallon fish tank went from slime green to Sparkling Clean. I shopped for a fish tank filter that did not hang on the side of the tank. This one makes so much sense, it's in the bottom of the tank - filtering the debris as they fall to the bottom. Easy install, add airline and place in bottom of tank. (Photo was taken in evening, does not truly reflect the clear, sparkling water.)
