Foam filter media - like for Aquaclear filter - for Eheim Pro

Looking for sources of DIY reusuable foam - similar to that used in
Aquaclear filters, for use in my Eheim Pro in place of the white foam pad
Eheim sells for $$$. This foam I believe is called "open cell, reticulated
foam" and probably has a size of 20 pores per inch or 30 pores per inch.
Found a source of such at 20 pores per inch. Not sure if that is fine
enough. Source is:
groups.google.com/groups?q=1%2...k+foam+is+true+*fish+grade&hl=en&lr =&ie=UTF
-8&oe=UTF-8&selm=35b069dd.74383538%40192.0.0.1&rnum=1

Also found a great source of bulk 75 foot roll of what appears to be
polyester filter material - $16 incl shipping:
