since ReefGeek isnt here to start it, ill get it going. in my reef i have a patial plenum due to it being a bowfront. i built it out of eggrate and 1/2"pvc. it stands approximately 1" tall covered in fine mesh nylon screen. i added approx 1" of sand over it then laid another layer of screen on top of it. then laid another layer of sand and agronite over it appox 2".
there are many sites describing the basic consruction of them just google "plenum+reef"
now here ya go big dawgs...break it down
