Pea gravel size for filter?

Interesting tip. How small are we talking here, like that fine aquarium gravel that's about like grape nuts and is usually artificially colored, or more like natural/ornamental pea gravel?

I'll have to check this out, still haven't done anything with the filter. May just scrap it till next season.
