HOw does this idea sound for a DIY filter cartridge?
Step one cut egg crate to appropriate size
Step two, rubber band filter floss around egg crate
Step three, when the cartridge get's clogged alternate changing half of the floss, the bacteria will continue to live in the other half and on the egg crate

You could even cut up the extra egg crate and put it in the bottom of the power filter to use like bio balls

The only downside I can think of is how to insert carbon if it's needed.
 
I think it sounds great. I would replace the filter floss with a sponge though so you dont have to buy replacements. Also if carbon is needed you can buy a 98 cents filter bag at petsmart, add the desired amount of carbon, and put it anywhere in the filter.
