DIY Sponge Filter
Take PVC or an Uplift Tube and Drill 1/4 in holes in a row of 4-8 every 90 degrees around it. Put a sponge around the holes and plug the bottom using something "fish friendly." Put an airstone in the uplift tube and Voila.

P.S. Im at school so i will upload pics when i get home... :)

Something like those right? I haven't actually made a new one yet but I have used them in the past. I have not been able to find a quality sponge to use yet. Will likely just order some replacement sponges for sponge filters to make my own.

For the most part, I have never gotten any of my sdponge filters, purchased or home made to actually "suck up" the fish waste. Not even really suck food to them really. They are more for the need for microinfusoria and biological filtration than actual mechanical. They worked great to feed baby cories right after hatching and all my fry iIhave ever had would readily pick at it for those little things we don't know are in the tank.
