5.5g shrimp tank- can I use a homemade sponge filter?

[gabysapha]

I have a 5.5g with a Whisper 10i filter in it. It takes up about 1/4 of the tank space, I really want to get that filter out.

I want to make this a cherry shrimp tank or a betta tank, so I think a sponge filter would be best.
I have a 2"x2" piece of foam that I put an airline into. Will that be enough filtration for the tank?

Thanks!

I have a 5 gallon with a Betta with a sponge filter that size. He is doing fine

I would put a rigid tube into the sponge and affix the airline to it, it'll work much better that way. It doesn't have to be a big one, I use 1/2" pvc on the ones I make.

That is what I do

Oh lovely! I'll have to look up how to do that. Do you put holes in the rigid tube? I'll start my research now

I have, but it doesn't seem to make a huge difference. I do drill a hole near the top of the ridge youtube to put the airline tubing into, it holds it into place.
