I had this idea pop in my head the other day so I tried it.
it might have some promise if it wasn't so ugly. A black sponge might look better, but I use these kind of yellow sponges (cheap dollar store giant car sponges) for sponge filters now and then. Th cell pores are tight but not closed and the sponge is stiff and easy to cut.
Given a few months, it will turn brown with bacteria anyway.
Plus I'm not real fussy of something actually works.
Anyways, I was looking at the overflow from this hang on the back standard filter box, and it occurred to me the nice clean water coming out just passed through a really thickly coated bio filter pad, so if there is anywhere tons of good bacteria is being shed all the time its right there.
I rigged a bunch of boxes, nets, bags, ect ect under the outflow and none really seemed unique and workable.
Then I remembered to keel it simple, a good engineering mantra.
So, ya take the big yellow stiff sponge, gut it and make a box, out of the sponge itself.
Theoretically, in my head the advantages are a last stage water filter, a nice place for bacteria to grow, being subject to a constant fresh flow of water (right out of a heavily laden bio pad).
I made wire clips to hang it snug right under the spillway, and it sticks out of the water about 1/2 inch. Then it occured to me this is cool, since you know by watching it that ALL the water from the filter is going right through the sponge, and not overflowing it. I'm sure in time as the sponge fills with bacterial slime, it will but it IS a sponge, a few squeezes in some clean water and it should be clean enough to contain the water and let it slowly seep out and not overflow the "spongebox".
it's a prototype and its rough but it seems to work just fine, if you can handle the ugly color. The placement doesnt actually take up much room at all, and I suppose if one wanted to it could be made as big or as small as you wanted it to be.
It's a basic idea i thought I'd toss out there.
I dunno if this has ever been done, if so, oh well. LOL
If not, here it is.
I like this idea better than a big old sponge filter block taking up space on the tank floor, which was actually my motivation for making it. Plus it doesn't make that annoying glug glug glug noise all day from the bubbles. Bacteria should colonize in this pretty quickly since the filter boxes bio-fiber pad is well coated and clogged with the stuff.
I wish I could find a dark green or black sponge.
Here is some pics.
