DIY Air-Driven Sock Filter w/Bio-Media ($4)

[johnnymax]

I made an air driven filter for my tank for $4 plus activated charcoal. I bough the parts from Dollar Tree.
It should be easy to clean, just launder the sock and rinse the inside with DECLORINATED water and reassemble. But at 50 cents a sock, I will just buy a few dollars worth and use new socks. I plan to wash it once a week and see if that is enough.

Components:
1 liter plastic storage container (2 for $1)
Water squirt toy for riser tube ($1)
4 scrubbies ($1)
1 pair black compression tube socks ($1)

Inside the filter I put a layer of gravel from an established tank to help inoculate the tank. Then a layer of activated charcoal and above that the scrubbies. Once assembled I cut a hole in the toe of a sock and pulled it over the top. I then doubled it up to double it.

Very creative never seen a dot filter like that one.

So they are called dot filters. I was looking at a sponge filter, but I wanted charcoal and bio-media in it. Originally I was going to buy filter sponge to wrap around the outside, but decided to try the socks first, because they were available and cheap. I bought black, so it looks like a sponge filter, which we are already used to seeing in a tank. I was surprised that over night my tank was noticeably clearer. I did not know if it could filter out the white particles in suspension from the crushed oyster shell and coral substrate.
Thanks for the thumbs ups!
