What I did, step by step:

  1. emptied an old internal filter of all the foam media
  2. made a hole in the basket for an airline (i just pushed the plastic bars through)
  3. put a glass / ceramic diffuser in the basket and connected up to my co2 supply
  4. put bio media (any type will do) on top of the diffuser and filled the basket back up
  5. attached the basket back to the powerhead
  6. i did this on a Fluval 1 internal filter i had lying around. Cheap, simple and easy to do

result = great co2 distribution around the tank
