Filtration suggestions for a 2.5g

[TheresaM]

I need suggestions for filtration for my 2.5g. I'm currently running a small PetCo air pump which is crazy loud and this sponge filter which was the smallest I could find on Amazon yet still seems huge in the tank. I'd even go with a small internal filter if something like that is available.

Thanks!

I used this in my 2.5g and it worked incredibly well.

Thanks! Was it quiet?

It is just as quiet as the air pump you're using with it.
