There's a link in post 28 on page 3. Keep in mind, my filtration was built to handle my bio load and I think that load could be hard for some to grasp, especially if someone's never kept rays as their poo is like no other fish and just wreaks havoc on standard type filtration. Can even cement together bead filter media. IF I skip a day feeding my tank can put away 4 lbs of food, so believe me, there's plenty of crap to test mechanical limitations.....
I don't think RFSs would work as the only source of mechanical filtration. I built them to get me through the week so I'm just changing socks on the weekends instead of 3 or 4 times a week. Socks are super easy to wash - just pitch them in the washing machine.
Sounds funny but do some digging - everyone cleans them this way.
