That was a very interesting and thought provoking article. I especially liked the part about "mixing media" in a cannister filter. I resemble that remarkProbably should not use any hard media in there as all that is inefficient. Best to just fill the whole thing up with simply plastic pot scrubbies that have 10 times the surface area. Read here and all the links.
Well I have a Sunsun 303B in my 75 gallon. Bottom tray 10/20 ppi Poret foam. Next two tray all pot scrubbies. After 7 months and no cleaning I still have full flow, crystal clear water just like the articles says. Gotta love not cleaning filters.That was a very interesting and thought provoking article.

Ironically I pulled out most of the filter sponge media in my Oase Biomaster 250 and replaced it with several different types of hard biomedia. I have noticed a progressive slowing of output from my 3 month old setup. I am now starting to think about moving back to the sponges. One nice thing about the Oase is the easily removable sponge prefilter cartridge. I can clean it once a week and keep most of the detritus from clogging the downstream media ...or sponges.
