diy sponge filter???

[tarpon]

Alright so I looked on YouTube at this video on a diy sponge filter. It was just an air pump run with a sponge on the end of the tubing.....is that really all it is????? Does that really draw water and debris in? I've never even seen a sponge filter so sorry for being clueless

I was wondering the same thing. I had assumed that you would have to reverse the air flow ( i.e suck rather than blow). Have to admit to being rather clueless.

Sponge filters are pretty simple, but arguably the best biological filtration you can get.

Roundar made some DIY sponges. If you look down towards the bottom of the first page, and also on the second page, you'll see pics. http://www.aquariumadvice.com/forums/f70/the-fishroom-and-all-things-fish-160275.html


There are also other designs. These are the filters I use ATI Hydro Sponge Filter #4
