i think all pumps can be modified into a needlewhell...

1) remove the impeller (remove the blade), usually its not sealed dead

2) use a simple bioball, cut it into half..meaning,remove one side of the "pins".

3) in the center of the bioball, make a hole big enuf to fit into the impeller body, but tight enuf so that it will not to drop out during operation.

4) some use super glue to stick the bioball and impeller together but i used silicon.

fix the the whole pump back and try....
