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.
