Plenum Thoughts

After researching plenums for the last week, I've decided to install one in my 40-gallon breeder. I know it may not result in a huge water condition difference but I don't think it will hurt either.

Quick question, has anyone ever used landscaping fabric to separate the plenum from the substrate?

I plan on using Flourite (rinsed 100 times) or Floramax then capping with ADA AS. I'm concerned that over time the fabric will become clogged thus producing a failed anoxic zone. I'm not pumping water through the plenum just relying on heat transfer.

FYI. These pics show the plenum upside down.

Rico, how'd you do with this?
I've got one set up in my new 65 gallon. I also placed a layer of bio balls and covered it with a mat I made of crochet mesh. I'll be placing a 1/2" layer of Saf-T-Sorb, 1/2" of Eco-Complete and then 2-3" of more Saf-T-Sorb. Just about ready to start the substrate layers and hoping to get feedback.

If you won't be using sand I would do like Chuck and use the knitting canvas to make sure it never clogs. I just set up a plenum on a 20 gal long but I used an undergravel filter.
