[midasman714]

is the graphic below a true depiction of how a sponge w/ a powerhead filter work?

and where can i buy a good sponge?? i looked at petco and petsmart, they don't have anything decent in size and price.

Pretty close you don't have to use a powerhead though air bubbles do it just as well. You have to cut some slots in the tube so there is a flow..

Well that could work. Doesn't really matter what sponge you use for a DIY sponge filter. Try automotive sponges for cars. Buy two of them ( each are about 2.5" thick 8"+long) and stack them put you intake through them with two slots where both sponges are and walla you have a sponge filter. Use very porous sponges though that are very soft and mushy when they come out of the package. When you use that power head put some gaskets around the intake of the Power head and force it into the tube so you get a nice perfect seal. You could even use a aquarium pump which I think would be more reliable than the power head. Plus you can add additional DIY filtration with it like a PVC biological tube filter.

Air will work well, but you'll get better mechanical filtration with a powerhead.

where can i get gaskets for the intake?

and i'm going w/ the powerhead since i have an AC30 just running on its on right now; figured it would be in my best interest to attach a sponge to it; heard good things.

You can get rubber gaskets any where just make sure it's a snug fit or you can order from marineland the rubber bands they use to hold the vinyl tubing on their filters and let me tell you those rubber bands have to be the strongest damn things in the world. If you get a leak out of that then the world is coming to an end lol. Just soak them in HOT water to loosen them up and stretch them over the vinyl tubing and connect it to the power head and it's all set.

one of those car wash sponges. got at at walmart since the only sponges i could find at petsmart and petco were small dinky ones that were way over priced.

so far so good. already i'm starting to see a dark area culturing up in the center.
