    I have a 3 gallon tank am looking for effective/easy-ish ways to make a sponge filter. My 3 gal was a betta and two ghost shrimp so I'm looking for ideas that would be delicate enough not to hinder them.

    The easiest way would be a big chunk of sponge, a plastic tube shoved deep into the sponge, an air stone in the tube, and an air pump to make the stone work- you can see pictures of them online. They aren't rocket science. The bubbles lift water and pull more water through the sponge. Unless you've got this stuff lying around it would probably just be cheaper to buy one, though. They aren't expensive.

    Agree, I would buy the first filter and see how they function.

    Sponge Filters are very inexpensive I would't monkey around with it, I'd just buy one.

    I just made one last night, YouTube has lots of videos on how to make them, LifeWithPets has a good one and I think Rachel O'Leary has a video too and there are some others that are good too. I had all the stuff on hand so I thought, why not for my platy fry tank. Looks a lot bigger then it is due to the magnification from the bowl. Seems to be working well, water was nice and clear this morning
